How long for? Don't know of a metallic treatment as such, but there are some filled resins
and elastomers you could use as a surface treatment. These are either extremely hard
ceramic filled products or softer rubber or  filled epoxies. These later are designed to
trap impinging  particles on the surface which then then wear out further impinging
particles rather than the underlying metal.
Come back direct if you need more details.
