Smoky Chrome / Black Chrome Plating Solution BMG-108.3 – Dark Metallic Chrome FinishProfessional Smoky Chrome Electrolyte for Black Chrome PlatingThe Smoky Chrome / Black Chrome Plating Solution BMG-108.3 from Betzmann Galvanik is a professional electroplating electrolyte designed to produce a dark, metallic chrome finish.Depending on the substrate, surface preparation and plating parameters, the resulting finish can range from dark grey and anthracite to a deep smoky black metallic appearance.Smoky Chrome is particularly suitable for applications where a high-quality dark metallic finish is required and can provide an interesting alternative to conventional black rhodium or black ruthenium finishes.Typical applications include jewellery, watches, automotive parts, design objects, electronics housings, fittings and high-quality metal components.What Is Smoky Chrome / Black Chrome?Smoky Chrome is a galvanically deposited dark chrome coating with a metallic appearance.The final colour and gloss level depend strongly on the surface preparation and the underlying coating.Depending on the process, the appearance can range from:Dark Grey → Anthracite → Smoky Black → Deep BlackThe best results are generally achieved on smooth, polished nickel, copper or gold surfaces and other suitable conductive substrates.Because the coating is very thin, it follows the existing surface structure very closely.The better the underlying surface is polished and prepared, the better the final Smoky Chrome finish will look.Ideal for Jewellery, Watches, Automotive Parts and Design ObjectsSmoky Chrome is particularly attractive wherever a premium dark metallic appearance is required.Typical applications include:Jewellery and jewellery componentsWatches and watch componentsAutomotive trimAutomotive componentsDoor handles and fittingsBathroom fittings and accessoriesElectronics housingsMobile phone housingsLuxury and design productsMetal accessoriesDecorative metal objectsModel makingSpecial componentsRestorationHigh-quality metal partsThe coating is especially interesting for frequently handled components where a hard, durable and visually distinctive surface is desired.Smoky Chrome as an Alternative to Black Rhodium and Black RutheniumWhen a dark metallic finish is required, black rhodium and black ruthenium are commonly considered.Smoky Chrome provides another option:Dark to black metallic appearanceCharacteristic chrome finishHigh surface hardnessVery thin electroplated coatingSuitable for decorative applicationsMetallic rather than painted appearanceThis makes Smoky Chrome particularly attractive for customers looking for a premium black metallic surface.Suitable Substrates and UndercoatsThe final appearance and quality of the black chrome coating depend heavily on the underlying surface.Suitable substrates or intermediate coatings can include:Nickel coatingsCopper coatingsGold coatingsGold flash coatingsOther suitable conductive surfacesFor a high-quality decorative finish, a smooth, polished nickel or gold intermediate layer is recommended.For example, brass components can first be provided with a suitable nickel or white bronze intermediate layer before applying the Smoky Chrome coating.Perfect Surface = Perfect Smoky Chrome FinishSmoky Chrome is not a coating designed to hide poor surface preparation.Quite the opposite:The coating reproduces the underlying surface structure very clearly.We therefore recommend the following preparation:Mechanically finish and polish the surfaceCompletely remove polishing residuesThoroughly degrease the workpieceActivate the surfaceRinse thoroughlyApply the Smoky Chrome coating without unnecessary delayGrease, oxides and other contamination can significantly affect the quality and adhesion of the coating.Activation Before Smoky Chrome PlatingThorough activation is particularly important for sensitive or noble-metal substrates.For suitable gold surfaces, for example, activation with 10% sulfuric acid can be used. The Betzmann Galvanik Smoky Chrome instructions specify activation of gold surfaces with 10% sulfuric acid for approximately 1–2 minutes, followed by thorough rinsing.The exact pretreatment must always be adapted to the particular base material and existing intermediate coating.Suitable for Bath, Pen and Tampon PlatingThe Smoky Chrome BMG-108.3 electrolyte can be used for different electroplating techniques, depending on the equipment and application.Bath PlatingIdeal for:JewelleryFittingsAutomotive componentsDesign objectsMultiple workpiecesPen PlatingParticularly useful for:Repair platingLocalised coatingCorrectionsSmall areasDifficult-to-reach areasTampon PlatingParticularly suitable for:Local repairsPartial surfacesLarge individual componentsMobile electroplatingOn-site finishing and repair workRecommended ElectrodeFor the Smoky Chrome process, we recommend:✔ Carbon / Graphite✔ PlatinumCarbon or graphite electrodes are an economical and practical solution for everyday applications.Platinum electrodes offer excellent chemical resistance and can be used at the upper end of the recommended voltage range.Stainless steel anodes are not recommended for this process.Technical Specifications – Smoky Chrome BMG-108.3PropertySpecificationProductSmoky Chrome / Black ChromeArticle NumberBMG-108.3ProcessElectroplated Black ChromeVoltage9–11 VTypical voltage with carbonapprox. 10 VVoltage with platinumup to approx. 11 VTemperature20–30 °CRecommended electrodeCarbon/Graphite or PlatinumBrightness L*approx. 65–70%Chromium content of coatingapprox. 99%Remaining componentCarbonDeposition rate at 10 V / graphiteapprox. 2 µm/min (point plating)Maximum coating thicknessapprox. 3 µmHardness as depositedapprox. 800 HVHardness after heat treatmentapprox. 1,500–1,600 HVCoating densityapprox. 7.2 g/cm³Storage lifeapprox. 1–2 yearsHigh-Hardness Black Chrome CoatingOne of the key advantages of the Smoky Chrome system is the high hardness of the deposited coating.The freshly deposited coating reaches approximately:800 HVWith suitable heat treatment at approximately 220 °C, the hardness can increase to approximately:1,500–1,600 HVThis makes Smoky Chrome particularly interesting for decorative components that are regularly handled or exposed to mechanical wear.Thin, High-Quality CoatingThe black chrome coating is very thin, with a maximum thickness of approximately 3 µm.With point plating at 10 V using a carbon/graphite electrode, a deposition rate of approximately 2 µm per minute can be achieved.Actual plating time depends on the workpiece, current distribution, electrode movement, surface condition and plating method.Operating Temperature and VoltageThe recommended operating temperature is approximately:20–30 °CThe typical operating voltage range is:9–11 VWith a carbon/graphite electrode, approximately 10 V is typically used.When using a platinum electrode, the voltage can be increased to approximately 11 V.Optional Heat TreatmentHeat treatment is optional and is not necessary for every application.Where increased mechanical hardness is required, the finished Smoky Chrome coating can be heat-treated at approximately:220 °CThis can increase the hardness from approximately 800 HV to 1,500–1,600 HV.Smoky Chrome – Premium Black Metallic FinishUnlike paint or powder coating, Smoky Chrome produces a true electroplated metallic surface.The result can provide:✔ Dark grey to deep black appearance✔ Metallic finish✔ Premium anthracite appearance✔ Very thin coating✔ High hardness✔ Excellent decorative appearance✔ Suitable for frequently handled componentsImportant: Decorative Final CoatingSmoky Chrome is primarily intended as a decorative final coating.It should therefore not be marketed as a standalone corrosion-protection system. Corrosion resistance depends on the substrate, intermediate layers, coating quality, thickness and the complete coating system.For high-quality decorative applications, the correct undercoat and surface preparation are therefore essential.Safety InformationElectroplating chemicals must be handled using appropriate safety precautions.When working with the electrolyte:Wear suitable protective glovesWear safety glasses or face protectionUse suitable protective clothingAvoid skin and eye contactEnsure adequate ventilationDo not inhale aerosols, mist or vapoursRead the current Safety Data Sheet before useDispose of electrolyte residues according to applicable regulationsAlways follow the current product label and Safety Data Sheet.Betzmann Galvanik – Professional Smoky Chrome PlatingWith the Smoky Chrome / Black Chrome Electrolyte BMG-108.3, Betzmann Galvanik provides a professional solution for users looking to create a premium dark, metallic chrome finish.Whether for jewellery, watches, automotive components, design objects, electronics, fittings or special metal parts, Smoky Chrome opens up numerous possibilities for creating a distinctive black metallic appearance.Product Advantages at a Glance✔ Dark to deep-black metallic finish✔ Premium anthracite / Smoky Chrome appearance✔ Suitable for bath, pen and tampon plating✔ Carbon/graphite or platinum electrode✔ 9–11 V operating range✔ 20–30 °C operating temperature✔ Approx. 800 HV as deposited✔ Up to approx. 1,500–1,600 HV after heat treatment✔ Very thin coating up to approx. 3 µm✔ Ideal for jewellery, watches, automotive, electronics and design✔ Professional electroplating quality from Betzmann GalvanikBetzmann Galvanik – professional electrolytes, electroplating equipment, electrodes and accessories for high-quality surface finishing.
