Summary for ni-w alloy plating Discussion
Ni-w alloy plating is discussed as a possible hard chrome substitute, with Domingos J C Spinelli asking for an update on the technology and its deposit characteristics. The thread excerpt shown here does not include a substantive technical reply, so it only establishes the question: by 1996 the reported properties of nickel-tungsten deposits looked promising for replacing hard chrome, and the author wanted to know the current status. George Shahin of Atotech is listed in the source, but no answer text is provided in the excerpt. Because the thread text available here contains no detailed response or comparison data, no firm conclusion about performance, bath chemistry, or commercial readiness can be drawn from this page alone.
Q. I would like to know about the current status of the technology of Nickel-Tungsten alloy plating – The last time I’ve heard about it was back in 1996, at that time the facts were pretty convincing regarding the deposit characteristics as being a possible candidate for Hard Chrome plating substitute. Would like to hear about it please.
Thanks

A. There has been a couple of papers presented at various conferences about this coating that list properties of this coating. Ni/W coating had about 5-10 times more wear with the Taber Abrasive test. Also the plating rate was much lower than chromium. If you would like more information please feel free to contact me.
