ALKALI PHOSPHATE AS ANTICORROSIVE FOR FRICTION LINING OR FOR SOLID LUBRICANT COMPOSITION IN FRICTION LINING

摘要

A description is given of the use of alkali phosphates as anti-corrosive agents in friction linings or in solid lubricant combinations used in friction linings and the amount of these phosphates in friction linings is generally 0.1 to 6 weight % and in solid lubricant combinations for this purpose it is generally 5 to 50 weight %. Trialkali phosphates are preferred as alkali phosphates and of these especially trisodium phosphate.
