【Abstract】 The advantages of using hard-solder, laser clapping, arc spraying, arc surfacing and other additive technologies to replace conventional centrifugal casting in sliding bearings manufacturing and the current technical level are described. At the same time, the composition of high temperature creep resistant babbitt alloy wire developed with additive manufacturing technology and the processing technology status of fine wire are expounded. The application of additive manufacturing in the field of sliding bearings and the development trend of babbitt alloy wire composition optimization and related supplementary technology are prospected. The problems of whether the excessive fine SnSb phase will accelerate the wear of shaft diameter and whether the additive of multi-layer arc surfacing will affect the bonding strength are discussed.更多还原
