What is electroless process?
Electroless plating, also known as chemical plating or autocatalytic plating, is a class of industrial chemical processes that create metal coatings on various materials by autocatalytic chemical reduction of metal cations in a liquid bath.
What is the process of nickel plating?
Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. The nickel anode is dissolved into the electrolyte to form nickel ions. The ions travel through the solution and deposit on the cathode.
What is autocatalytic deposition?
Autocatalytic (Electroless) plating, also known as electroless plating, is a plating process which involves deposition without any current applied. The process is a chemical reaction and is autocatalytic. The deposition rate is normally 12.5 – 25 µm (. Typically nickel and copper are used in electroless platings.
What is electrodeposition method?
Electrodeposition is a well-known method to produce in situ metallic coatings by the action of an electric current on a conductive material immersed in a solution containing a salt of the metal to be deposited.
What voltage is nickel plating?
Nickel Plating Set the rectifier at 1-1/2 to 2 volts with the solution between 120º F and 140º F (consult your plating solution label for temperature requirements).
Why is nickel used in plating?
Nickel plating provides a unique combination of corrosion and wear resistance. It can add brightness, lustre and appeal. It also provides excellent adhesion properties for subsequent coating layers, which is why nickel is often used as an ‘undercoat’ for other coatings, such as chromium.
What are the limitations of electroless plating process?
The only disadvantage to the electroless process is that the solution needs to be monitored throughout to ensure that its concentration of metal ions is kept topped up. Since we monitor all our plating process in any case to ensure quality across the board, this hardly qualifies.
What kind of process is the kanigen process?
The KANIGEN® process consists in electroless deposition without any external source of electricity. In this process the work piece is immersed into an aqueous process solution with a specific content of nickel ions. During the process these ions are reduced into metallic nickel.
What kind of alloys can kanigen LP process?
KANIGEN® LP system is a low phosphorous electroless nickel process designed to deposit a uniform and hard nickel-phosphorous alloy onto a great variety of metals, alloys and non conductors.
Why do you use kanigen for friction control?
Friction control: Kanigen® phosphorus content creates a natural lubricity that minimizes heat buildup and reduces scoring and galling. The consistent smoothness of Kanigen® distributes the effects of friction evenly across a wear surface. This attribute can be further enhanced by surface polishing
