Repair of the Coal Mill Gear Shaft by Supersonic Thermal Spraying with Ultrafine WC-Co Composite Powder AITranslate
Abstract AITranslate
The large-sized coal mill gear shaft was repaired by supersonic thermal spraying with WC-Co composite powder synthesized by in-situ reaction. The microstructure, phase composition and mechanical properties of the coating are characterized. The test results show that the coating prepared by supersonic thermal spraying with ultrafine WC-Co composite powder could tightly bond with the matrix of the gear shaft with compact microstructure, small amount of decarburized phases formed at high temperature in the coating, distinctly better surface hardness and wear resistance. Therefore, the excess wear of the shaft can be remedied,and the life of the machine can be prolonged with remarkable economic benefit.
