High temperature lubrication is usually dependent on direct chemical reactions involving the lubricated material, the lubricant, and the atmosphere. Extreme conditions of operation promote excessive chemical reactions that are manifested in corrosive wear. Friction and wear experiments show the influence of various atmospheres, lubricants, and materials, at temperatures to 1500 F. Gaseous halogen-substituted methane derivatives offer promise for solution of high temperature lubrication problems.
Data reported include effect of sliding velocity on friction of steel surfaces with and without performed films of Fe3O4, effect of air on lubrication of cast Inconel riders sliding against an Inconel disk with graphite as the lubricant, effect of number of chlorine atoms substituted in CF4 on reactive gas lubrication of mild steel specimens. and effect of temperature on wear and friction of metals. 3.5.9
