Electro-less nickel plating is an autocatalytic chemical reduction process, without the use of electrical current in the plating process. It includes the cleaning and activation, electro-less nickel plating and chromium-free passivation and DI rinses. The benefits includes: excellent corrosion resistance, uniform plating thickness, excellent adhesion, low coefficient friction, excellent wear and hardness performance. We can process both hard disk drive components and electronic components.
