Abstract
The invention discloses a preparation method for improving the surface performance of a high-damping MnCu alloy, and relates to the technical field of surface treatment of metal alloys. According to the preparation method, a laser cladding technology is adopted for preparing a FeCoCrNiMn high-entropy alloy coating on the surface of a high-damping MnCu alloy matrix; and then a high-current pulsed electron beam technology is adopted for conducting surface alloying and element homogenization treatment on the FeCoCrNiMn high-entropy alloy coating obtained after laser cladding, so that the surface abrasion resistance of the MnCu alloy is improved, and meanwhile the high damping characteristic of the MnCu alloy is guaranteed.
