Titanium bolt or semiauto receiver durability/wear compared to carbon or stainless steel

[Rateoftwist]

I am not a materials speciailist, just a high power rifle enthusiast. Does anyone have any experience with titanium actions?
1. Do they hold up or have issues with steel bolt lug locking, lugging and bearing surface demonstrating accelerated wear? I imagine heat treat, alloy composition and surface treatments could change wear.
2. Any recommended alloy or surface coating recommendations used for these issues?

Hi,

FWIW..Titanium has pretty bad wear resistance.....that is why the aerospace world has spent and continues to spend millions of dollars in creating and testing surface film lubricants geared specifically for Titanium.

Titanium Alloys - Wear Resistance

The wear resistance of titanium alloys is quite poor. It can be enhanced by any number of surface treatments such as enhanced surface films, conversion coatings, electrolytic and electroless plating, thermal spraying, nitriding and shot peening. These processes are reviewed for titanium herein.

Improving the wear resistance of titanium alloys under high contact loads - Metal Science and Heat Treatment

Ion-plasma application of wear-resistant coatings of an alloy of the system Fe−C−Cr−Ni−V−Ti containing interstitial phases (carbides, nitrides, borides) to (α+β)-titanium alloys makes it possible to enhance considerably their wear resistance under high contact loads (up to 300 N/mm2).
