Beschreibung
Zusammenfassung:	The invention discloses a titanium alloy surface bionic high-entropy alloy structure wear-resistant layer and a preparation method and application thereof, and the preparation method comprises the following steps: S1, pretreating the titanium alloy surface; s2, high-entropy alloy containing Co, Al, Cr, Ti, Nb and V is subjected to laser cladding on the surface of the pretreated titanium alloy, a bionic high-entropy alloy structure wear-resistant layer on the surface of the titanium alloy is formed, the high-entropy alloy comprises CoAlCrTiNbV, Co7.5 AlCrNbTiV and Co20AlCrNbTiV, and a bionic mussel type structure configuration is formed by adopting a dislocation cladding method; and S3, detecting, analyzing and representing the bionic high-entropy alloy structure wear-resistant layer on the titanium alloy surface. When the titanium alloy surface bionic high-entropy alloy structure wear-resistant layer is applied to the petroleum drill rod, the wear resistance of the petroleum drill rod can be improved. 本发明公开了一
