Sliding surface working method using wire-explosion coating

摘要

There is disclosed a sliding surface working method using wire-explosion spray coating according to which the inner surface of an aluminium alloy cylinder is wire-explosion spray coated using a molybdenum wire, molybdenum-tungsten alloy wire, or tungsten wire. Next, the inner surface is alternately and repeatedly wire-explosion spray coated by alternately wire-explosion spraying a carbon steel wire and a wire of a material having good seizure resistance and wear resistance characteristics. Finally, the inner surface thus coated is ground and finished.
