Sliding tests were run with representative cobalt, nickel, and iron base combinations at 80 and 1600 deg F on a lowspeed friction apparatus. Temperature cycle tests were made on these materials, and several possible solid lubricants were investigated. The following results were obtained: (1) Stellite 6 gave the best performance at both 80 and 1600 deg F. (2) Up to 1200 deg F, considerable surface damage resulted with Inconel X and other Ni--Cr alloys. Above 1200 deg F, friction and wear reduced, and this effect is attributed to the oxide film. (3) Stainless steels appeared unsatisfactory. (4) Oxidized copper plate and cobalt oxide gave surface protection at 1600 deg F. (auth)
