Golf head nickel chrome plating corrosion  

++++

We are trouble shooting some inconsistent nickel chrome plating corrosion results on a 1025 low carbon steel golf club head. The interior deep sharp corners get inconsistent plating coverage, and the 48 hour salt spray tests are varying.

Are there any recommendations for pre or post plating operations which may improve?

Ever passivate a plated part in case there is some residual free iron?

It is a Trivalent chrome process.

Thanks

You should take a look at racking to see if a different racking method will produce better plate distribution in the low current density corners. It may be necessary to increase overall nickel thickness in order to get a thick enough nickel deposit in the low CD ares to pass salt spray. If you are using single layer bright nickel, a change to duplex nickel will improve salt spray performance. Any of the major suppliers of nickel plating processes can help you with that.

I'm suprised you consider trivalent durable enough for golf clubs. I've been turning this type of work away.

Am I missing something?

I have over 25 years of experience manufacturing golf clubs and additional experience working with different Companies plating golf clubs in California.

The problem described is a common problem in plating golf clubs. The best feasable solution is to plate duplex nickel. The corrigation lines and stamps are the typical areas of corrosion failures. This is due to the extreme LCD areas and geometry involved. Rack positioning will not resolve the problem. Conforming auxilliary anodes might help but will be very costly.

You should be able to increase the salt hours by 2 to 3 times by using duplex nickel.
