DEVELOPMENT OF ANTIFRICTION COATS FOR SLIDING BEARINGS OF COMPRESSORS

摘要

The reliability of antifriction coats of sliding bearings of compressors depends a great deal on the coating method. The results of study of wear of specimens based on the disk-block (shoe) scheme are reported. The characteristics of antifriction coats from babbit B-83 alloy applied by centrifugal casting method, plasma-jet spraying, and galvanic deposition are compared. The influence of porosity and density of babbit coats on their antifriction properties is studied.
