  • Antifriction paste and solid antifriction coating prepared from same
    Patent number: 4329238
    Abstract: An antifriction paste containing epoxy resin, molybdenum disulphide, graphite, aluminum, copper, alumosilicate and polyethylenepolyamine, the components being used in the following proportions (in parts by weight):epoxy resin: 40-80molybdenum disulphide: 15-30graphite: 10-15aluminum: 5-10copper: 5-10alumosilicate: 8-15polyethylenepolyamine: 5-10.The antifriction paste may also contain a solvent for the epoxy resin in an amount from 5 to 30 parts by weight. This paste is suitable for both small-and large-size friction assemblies. On the basis of this paste a solid lubricating coating with high antifriction performance is produced. Thus, a coefficient of sliding friction f.sub.fr. at a sliding speed V=0.06 m/s at a load P=10 kgf/cm.sup.2 is 0.2; linear wear rate I.sub.h under the same conditions is 1.0.10.sup.-9, and service life is as high as 500 km.
