| description | The invention discloses a preparation method of a modified cobalt-based plasma cladding coating applied to a high-temperature wear environment, which is characterized in that a Q235 plate is used as a matrix, WC powder is added into Stellite21, and a plasma cladding technology is adopted to prepare the wear-resistant coating. According to the method, the situation that a large number of holes appear after WC is added and WC cannot be completely decomposed to form a strengthening phase with Co is considered, so that the WC in the coating is uniformly distributed and decomposed by adopting a plasma remelting technology after plasma cladding, and the strengthening phase is formed. XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscope) result analysis shows that the structure obtained after remelting is more uniform, and although the surface hardness is reduced compared with that before remelting, the 600 DEG C high-temperature abrasion loss is greatly reduced, and the abrasion resistance is greatly impro |
