This study aims to prepare an iron-based alloy laser cladding coating with excellent wear resistance under high temperature and high speed conditions. By selecting steel based material metal discs as the basic material for cladding coatings, using iron powder as the main component, combined with high-purity chromium carbide powder and tungsten disulfide, and utilizing the auxiliary effect of laser cladding machines, iron-based alloy laser cladding coatings are prepared. The wear resistance of the coating was tested using a testing machine in a high-temperature and high-speed friction environment. The test results showed that the friction coefficient and wear rate of the coating reached 0.3 and 20% respectively at 400 ℃, belonging to a relatively high range. Moreover, at this temperature, the coating became smoother after friction and did not exhibit more severe particle wear. Under the 1500r/min test conditions, the friction coefficient of the coating showed a low state, and there were no obvious pits or scratches on the coating. From this, it can be seen that the coating has high wear resistance in high-temperature and high-speed environments.
