Titanium alloy surface ion plating high-entropy alloy wear-resistant coating and preparation method thereof

The invention discloses a preparation method for ion plating of a high-entropy alloy wear-resistant coating on the surface of a titanium alloy. The method comprises the following steps: 1, calculating to obtain components of a BCC type high-entropy alloy wear-resistant coating and an FCC type high-entropy alloy wear-resistant coating; 2, smelting to prepare a BCC type high-entropy alloy target material and an FCC type high-entropy alloy target material; 3, mounting a target material; fourthly, the titanium alloy base body is installed and cleaned; 5, a CrN base layer is prepared through deposition; sixthly, an FCC type high-entropy alloy coating is prepared through deposition; and seventhly, the BCC type high-entropy alloy coating is prepared through deposition. According to the high-entropy alloy theory, the coating structure is designed, the target material is prepared, the high-entropy alloy wear-resistant coating with the FCC/BCC characteristic is prepared on the titanium alloy surface through fractional
