Dynamic impact method for simultaneously performing peening and film formation on a substrate hit by metallic glass particles

摘要

PROBLEM TO BE SOLVED: To provide a dynamic impact method for simultaneously performing peening of a substrate surface and forming a thin film of metallic glass on the substrate surface in order to simultaneously enhance the surface hardness, fatigue resistance, fracture strength and corrosion resistance of the substrate. A metal glass or liquid metal alloy thin film is prepared by preparing metal glass particles 1 or liquid metal alloy particles and causing the metal glass particles 1 or liquid metal alloy particles to collide with a substrate 2 to cure the surface of the substrate. To improve the corrosion resistance of the surface of the substrate 2. [Selection diagram] Figure 1
