• Introduction :-
Electroless Nickel Plating is a chemical plating process in which deposition take place by way of dipping i.e. auto catalytically.
Since the process requires no electric current thus the result is a very Uniform Coating in each and every area of the job (like a blind holes, threads, channels, recesses or internal areas receive the same amount of plating as sharp corners, edges or flat surfaces). Thus plating ovality can be
occur within 5 microns so that post grinding of machining to size can be eliminated.
• Features of Electroless Nickel Plating :-
• Uniform Deposition.
• Corrosion Resistant.
• High Hardness (45 HRC - 70 HRC).
• Abrasion Resistant.
• Low Friction and Wear Characteristic.
• Quick Release Properties.
• Conductivity.
• Solderability, bondability.
• Weldability.
• Diffusion barrier.
• Brazeability.
• Compressive Stress, Good properties.
• Non magnetic or magnetic deposits.
• Finish - Bright as well as Dull (matt). |
