Abstract: A super-elastic titanium alloy for medical use consisting essentially of: molybdenum (Mo) as a ? stabilizer element of titanium (Ti): from 2 to 12 at %; an ? stabilizer element of the titanium (Ti): from 0.1 to 14 at %; and the balance being titanium (Ti) and inevitable impurities. The ? stabilizer element is at least one element selected from the group consisting of aluminum (Al), gallium (Ga) and germanium (Ge).

Abstract: A plasma sprayable powder for coating surfaces such as cylinder bores of an internal combustion engine, comprising grain size agglomerates of (i) a plurality of solid lubricant particles selected from the group consisting of graphite, MoS.sub.2, BN, CaF.sub.2, and LiF; and (ii) fusable ingredients adjacent the solid lubricant particles, the ingredients being air-hardenable upon friction-promoting-use, and the lubricants and fusable ingredients being agglomerated together by a low melting medium in the grains.A solid lubricant coating system for use with a metal interface subject to high temperatures and wet lubrication, comprising agglomerates of particles of (i) solid lubricant particles selected from the group consisting of graphite, boron nitride, molybdenum disulfide, lithium fluoride, NaF, WS.sub.
