Black Chrome - Smoky Chrome by Betzmann Galvanik      This dark anthracite to slightly black shiny look is now popular for many car parts or cell phones and is a very good alternative to black rhodium or black ruthenium. Alternative to black rhodium or black ruthenium.   Black chrome is a spectacular finish and always an eye catcher.   Recommended electrode: Carbon Electrode 10 Volt - Platinum electrode 11 Volt.     Plating on degreased copper, nickel, gold flash or any other gold plating.    Operating Conditions and Deposit Data Voltage Range 9 – 11 volts (see notes) Temperature 20 – 30 °C Lightness (L*) of deposit 65 – 70% Electrode Carbon or Platinum Electrode (see notes) Chromium content in plate 99% (balance carbon) Plating Rate at (10 volts, Carbon Electrode) Approx. 2 micron per minute (spot) Maximum plating thickness 3 microns Hardness (as plated) 800 Hv (see notes) Hardness after heat treatment 1500 – 1600 Hv (see notes) Density of deposit 7.2 g/cm3 Stress Hi stress Special storage requirements None Shelf life 1 – 2 years Health and Safety classification Not classified as dangerous Special considerations None Transport (UN number) None: Not classified as dangerous for transport   Notes:   Heat treating at 220 °C increases the hardness of the deposit from 800 to 1600 Hv. The voltage should be raised from 10 volts if using a Carbon Electrode to 11 volts whenusing a Platinum Electrode. We strongly advise against the use of stainless steel anodes for most of our plating processes. Plating rates are calculated over a sample area which is permanently covered by swab.       Labelling acc. to CLP-VO: Symbol word: Caution!  H319 Causes severe eye irritation.
