I used to use a chromium plating called ARMOLOY NTDC where I worked previously. Armoloy is an American company (Philadelphia I think). The coating is extremely hard, (about 70HRC / 1100HV), satin in appearance, and works wonders. In our experience it adhered and lasted much better than either Nickel or Silver. We used it for Nuclear applications mainly, where exfoliation of Nickel had been a problem.

Carpenter Steel makes an austenitic stainless steel called 'Gall Tough' which works well. There is a competitors product called 'Nitronic 60'

If silver plating is not used, there are lots of different dry film lubricants, which are affordable solutions, particularily the ones that come in a spray can and do not have to be baked. They are not as good as baked, but would work fine for a touch up.

Mike - Another anti-gall coating is manganese phosphate. It also holds an RP oil very well for corrosion protection. The production process is similar to zinc phoz. Ask your chemical vendor for info.
