avoid the deposition of micro-particles of micrometer scale in the coating, which has a negative impact on the performance of the erosion resistant protective coating on the surface of precision parts. Therefore, how to eliminate or reduce the micro-particles in the anti-erosion coating prepared by arc ion plating is also one of the focuses of current research.
