CVD method of forming self-lubricating composites

摘要

An article having a multiphase composite lubricant coating of a hard refractory matrix phase of titanium nitride dispersed with particles of a solid lubricating phase of molybdenum disulfide is prepared by heating the article to temperatures between 350 DEG and 850 DEG C. in a reaction vessel at a reduced pressure and passing a gaseous mixture of Ti((CH3)2N)4, MoF6, H2S and NH3 over the heated article forming a multiphase composite lubricant coating on the article.
