Abstract
Description
technical field
[0001] The invention relates to a method for preparing a wear-resistant coating of a high-precision roller, and belongs to the technical field of wear-resistant coating preparation. Background technique
[0002] In industrial production, a high-hardness reinforcement layer is often prepared on the surface of the workpiece to improve its wear resistance. At present, thermal spraying and remelting technologies are usually used at home and abroad to prepare wear-resistant layers to achieve wear-resistant strengthening on the surface of workpieces, mainly including supersonic flame spraying (HVOF), atmospheric plasma spraying (APS), plasma surfacing, high-frequency induction melting, etc. Deposit, vacuum fusion, spray welding, etc. The wear-resistant coating prepared by single thermal spraying technology such as HVOF spraying and APS spraying is usually mechanically bonded to the substrate, and its bonding strength is difficult to meet the needs of actual workin...
