METHOD OF APPLYING MULTILAYER METAL COATING TO RESTORE WORN PARTS AND ITS MODIFICATION Russian patent published in 1997 - IPC

FIELD: coatings. SUBSTANCE: coatings are applied by way of thermal decomposition of VI-VII group metal carbonyls under reduced pressure, in which method one of layers is applied from mixture of VI group metal carbonyl and carbon monoxide at volume ratio of vapors 1:(5-10), respectively, and temperature 500-595 C or from volatile organocopper compound vapor, and next layer from mixture of VIII and VI group metal carbonyls at volume ratio of vapors 10:(1-5) and temperature below 500 C. As copper compound, copper diketonates and iminoketonates are used. EFFECT: improved procedure. 3 cl, 1 tbl
