Galling - Wikipedia, the free encyclopedia
Galling , according to ASTM standard G40 (2006), is: “a form of surface damage arising between sliding solids, distinguished by microscopic, usually localized, roughening and creation of protrusions ...

The information on this page concerns stainless steel. Stainless steel consists of four categories: austenitic, ferritic, martensitic, and precipitation hardening PH. ... These findings indicate that gall-resistant alloys can economically bridge the gap between corrosion, galling, and metal-to-metal wear resistance.

The problem is that the 7075-T6 is galling. Can anyone recommend two metals that would work well together in this situation without lubrication? Or possibly a metal/poly combination. Or even a web site or book that I might reference to find metal on metal recomendations.

Titanium Carbide Parts Overcome Galling and Pick-up ... Exposing the Ferro-TiC® titanium carbide micrograins at the working surface leaves them in relief and, in effect, minimizes metal-to-metal contact. Their smooth, rounded structure offers an extremely slippery and non-abrasive surface for contact.

When metal-to-metal galling is a problem or in high heat situations, special alloys are chosen for their lubricity and heat resistance (usually a result of added nickel). Filler materials with high nickel, chromium, tungsten or cobalt content tend to exhibit good wear resistance.
