Description

Technical field [0001] The invention belongs to the field of surface technology, and particularly relates to a composite coating material used in the mold of a metallurgical continuous casting machine, and a manufacturing method and equipment. Background technique [0002] The metallurgical continuous casting machine mold has a wide range of applications in the metallurgical industry. At present, the mold of metallurgical continuous casting machine is generally made of copper alloy to ensure that the mold has good thermal conductivity. In view of the high temperature and wear characteristics of the metallurgical continuous casting machine mold, the metallurgical continuous casting machine mold is required to have excellent high temperature wear resistance. For this reason, people increase the service life of the metallurgical continuous casting machine mold by electroplating various types of metal coatings on the surface of the copper alloy continuous c...
