METHOD OF CLADDING OF FRICTION UNIT METAL SURFACES, METAL CLADDING LUBRICANT AND METHOD OF ITS MANUFACTURE Russian patent published in 1996 - IPC

FIELD: mechanical engineering: lubrication of friction units of trucks and cranes. SUBSTANCE: in offered method of cladding of friction unit metal surfaces used as powder filler of metal cladding lubricant is ultradispersed nickel = containing powder with size of metal particles equal to 10 - 90 nm and consisting of 20 - 50 mass % of nickel, 80 - 50 mass % of charcoal at the following ratio of components: 0.1 - 5 mass % of powder filler and up to 100 mass % of mineral or synthetic oil. To prepare powder filler charcoal and nickel oxalate or nickel formate are mixed and rubbed together. Mass of materials taken in ratio of (1 - 15):(1 - 5). Mixture is subjected to heat treatment in inert medium to form powder. Another method of obtaining powder filler is impregnating of charcoal with solution of nickel nitrate with subsequent filtering and heat treatment. EFFECT: enhanced quality of lubricant. 6 cl, 5 tbl
