PS-300 anti-friction coating
PS-300 anti-friction coating
(OP)
NASA developed PS-300 as a plasma sprayed coating consisting of chrome oxide, silver and barium fluoride/calcium fluoride eutectic in NiCr binder. Has anyone ever used it or know of a company that can apply it? Last time I checked into having the rotary engine endplates coated, Flame Spray, in San Diego, suggested using a soft grade of tungsten carbide. While that may work I am also looking at alternatives. PS-300 does not require diamond grinding whereas tungsten carbide does.
Titanium nitride had poor adheasion to the aluminum.

UEL in the UK has the rights to the Norton rotary and does not sell parts for motorcycles. I got the center case and rotors through another parts dealer that somehow "appropriated" what he called "out of tolerance" aircraft parts. I had so many problems dealing with him that I am now building it myself and redesigning parts.
