不锈钢镀金前Watts Nickel Strike和Woods Nickel Strike有什么区别？

不锈钢镀金前Watts Nickel Strike和Woods Nickel Strike有什么区别？

Woods Nickel Strike是什么含义？ 有木头打底的吗？

这里的WOOD是木纹的意思,Woods Nickel Strike是一种型号/牌子是Nickel的木纹不锈钢

All mechanical parts in module made of Invar material shall receive the
Wood’s Nickel Strike treatment prior to plating. This treatment will ensure
proper plating adhesion to part.


Woods Nickel Strike是电镀前的一道工序，以确保镀层的附着力。

Procedure for Nickel Strike (Wood’s Nickel)
(activation of stainless steel, nickel and nickel alloys)

Plating on stainless steel, nickel and nickel alloys requires that the basis metal be given an activating treatment before electroplating to assure adhesion of coatings. The recommended treatment is to clean then to strike the parts in a Wood’s nickel strike solution. The work should be
cleaned in a manner consistent with the base
material, rinsed, made
cathodic, with nickel striking taking place at 15 to 20 asf for one minute,

or until a continuous nickel plate is obtained. The work is then rinsed
and plated per requested specification.

谢谢楼上二位

不锈钢镀金前Watts Nickel Strike也能达到很好电镀层结合力的吧？

我找到一些资料贴出以共享，

Wood's Nickel is a nickel strike solution invented by Donald Wood[dec.] of Hill-Cross for the activation of stainless steel. Stainlesssteel quickly acquires a natural passivated film which is difficultto remove, and difficult to plate onto with good adhesion. The Wood'sNickel Strike contains a lot of HCl and is designed to simultaneouslydissolve the passivation layer and deposit nickel onto the stainlesssteel. There areother activation/striking solutions, but Wood's nickel is thestandard.
