●维修材料与原零件材料结合力要好,否则在零件高速转动时容易脱落失效。

●维修材料的硬度要好，才能经得起高速转动的需要。

●维修材料的耐磨度要好，确保修复后较长的使用寿命。

●在维修过程中不能使零件产生热应力和变形，影响零件转动。

●要能对磨损严重的零件进行修复，在大厚度修复的同时还要解决好很高的结合力，确保修复效果。

●The bonding force between the maintenance material and the original part material should be good; otherwise, it is prone to fall off and fail when the part rotates at high speed.

●The hardness of the maintenance materials must be good to withstand the requirements of high-speed rotation.

●The wear resistance of the maintenance materials should be good to ensure a longer service life after repair.

●During the maintenance process, the parts must not be subjected to thermal stress or deformation, which could affect their rotation.

●To be able to repair severely worn parts, while conducting large-thickness repairs, it is also necessary to ensure a very high bonding force to guarantee the repair effect.
