A low coefficient of friction (0.03-0.06) which, unlike graphite, is inherent and not a result of absorbed films or gases;
A strong affinity for metallic surfaces;
Film forming structure;
A yield strength as high as 3450 MPa (5 x 105 psi);
Stability in the presence of most solvents;
Effective lubricating properties from cryogenic temperatures to about 350oC in air (1200oC in inert or vacuum conditions).
A combination of molybdate and water soluble sulfides can provide both lubrication and corrosion inhibition in cutting fluids and metal forming materials. Oil soluble molybdenum-sulfur compounds, such as thiophosphates and thiocarbamates, provide engine protection against wear, oxidation and corrosion. Several commercial manufactures supply these additives to the lubrication industry.
