Product information "Nickel Strike"
The new nickel strike from Betzmann Galvanik makes steels and stainless steels suitable for electroplating.
Nickel-strike or the so-called "nickel-on-nickel" was already used as an electrolyte in the 19th century. Today, nickel strike is indispensable in electroplating to prepare high-alloy stainless steels and steels for electroplating. This is because the oxides present on the surface of high-alloy metals impair the adhesive strength of the coating applied by means of bath electroplating or pin electroplating / pad electroplating. Therefore, the pretreatment with the impact nickel / nickel strike is necessary.
This is how the Nickel-Strike from Betzmann Galvanik works:
Pretreatment with Nickel-Strike prepares the surface for subsequent coatings. This is suitable for galvanic and electroless treatment. It etches the surface of the workpiece, dissolves contained chromium and creates a base layer of nickel in the course of this reaction. This micro-thin nickel layer of 0.5 - 1 µm now forms a reliably strong adhesive base for further coatings.
Ideally, you apply an intermediate layer after the treatment with impact nickel and before the final coating of the workpiece. This consists of copper or electroless or electroplated nickel. Whether the coating is applied by the bath electroplating or pin electroplating / pad electroplating processes is not relevant.
Areas of application for nickel strike
The nickel strike process covers a very wide range of applications. In addition to the pretreatment of high-alloy steels and stainless steels, a wide variety of non-ferrous metal alloys also require this pretreatment. These include, above all, alloys with silicon, magnesium, manganese, lead, tungsten or titanium.
Already nickel-plated objects that are exposed to air over a longer period of time lose the typical properties of the coating. These are then so-called passivated nickel layers, which a dip in Nickel-Strike reactivates.
Nickel-Strike for galvanic and electroless application
Nickel-strike is suitable for all electroplating processes from bath electroplating to pin electroplating / pad electroplating as well as for the electroless process.
Fields of application:
Stainless steel
Nickel
Before use:
Completely remove grease and oil especially thoroughly by using alcohol. Please remove dirt and rust with appropriate tools. Only handle the object with disposable gloves and in this way reliably prevent the transfer of skin grease to the surface.
Electroplating process (with power supply):
Anode bath electroplating: Graphite, nickel or platinum anodes.
Anode pin electroplating / pad electroplating: Graphite, nickel or platinum anodes, alternatively stainless steel anodes possible.
Parameters (these may vary, please test):
Bath electroplating: 1.5-4.5V (approx. 2.5-3V recommended at 10cm distance)
pin plating: 2,5-5V (approx. 3V recommended)
Current density: 8.5-25A/dm² (up to 50A/dm² with bath movement)
Working temperature: 20-50°C
Deposition rate: approx. 0.03µm/min at 10A/dm² and 20°C
pH value: 1
Attention:
for stainless steel: anode on positive pole - workpiece on negative pole
for nickel: anode on negative pole - workpiece on positive pole
Treat the workpiece with the pin plating or immersion process for about 10 to 60 seconds. Rinse the workpiece briefly afterwards. Immediately continue processing objects made of aluminum to prevent renewed oxidation.
Currentless process (without power supply):
Place the electrolyte in a suitable vessel and heat the impact nickel to a temperature of 35 - 50°C. Now place the object to be coated in the immersion bath for 0.5 - 3 minutes and finally rinse briefly. Please immerse aluminum objects at room temperature for a maximum of 0.5 - 1 minute!
Optionally, use the stop tickel tempered to room temperature. In this case, however, take into account the longer dwell time in the immersion bath.
To prevent renewed oxidation, objects treated with Nickelstrike should be further processed within 10 - 30 minutes. In the case of aluminum, immediate further processing is required.
Caution: Always use gloves and protective goggles and do not inhale the fumes / aerosols. Use only in well ventilated areas!
