Zinc Coating Alternatives
Zinc Coating Alternatives
(OP)
Hi All,
I have some washers that appear to be zinc plated. We have been using them on our products. While the washer is used internal to the product and not exposed to the elements, there are instances of high humidity that occur. My limited experience with Zinc coatings is that they won't hold up without rust appearing from the base metal for long. What are oyur recommendations for a cost effective coating to replace the zinc over hardened steel. Also, if you feel I am wrong with my assumption that the zinc will show rust through please let me know.
Thanks
Bill

Your existing plater should be able to do both operations.

I am surprised however, to hear that the hardened, plated washer could have corrosion problems in a normal ambient environment in less than 5-10 years!
