1. Improve the anti-adhesive wear performance In and Mo have good anti-adhesive wear performance. Electroplating or plating a layer of In or In alloy on the surface of the repair layer of the beneficiation equipment, and adding Mo to the spray layer can significantly improve the anti-adhesive wear. performance.
2. Improve the metallographic structure The basic phases of carbon steel are ferrite and cementite, and an appropriate amount of alloying elements are added to strengthen them. Elements such as Ni, Si, A1, and Co are usually dissolved in ferrite to form solid solution strengthening; Cr, w, Mo, v and other elements can replace Fe in cementite to form high-hardness carbides, which can be formed on soft substrates. Uniform distribution of hard points is an ideal wear-resistant structure.
3. Forming a porous surface There are many micropores on the surface of the repair layer of the beneficiation equipment, which can store lubricating oil, improve lubricating conditions and improve wear resistance. The porous coating obtained by anodizing after spraying and electroplating can improve the wear resistance.
4. Improve the hardness Increasing the hardness of the repair layer of the beneficiation equipment can improve its wear resistance. However, if the hardness is too high, the brittleness increases accordingly, and the wear resistance decreases. Therefore, the equal hardness point of view should be advocated in the maintenance of mineral processing equipment, so that the hardness of the repair layer should be as equal to the original as possible.
5. Refinement of grains The grain-refined repair layer has more grain boundaries in the same area, the strength and hardness of the repair layer increase at the same time, and its wear resistance is also improved accordingly
