Alkali solution treatment method for improving frictional wear performance of metallic glass and application

The invention relates to the technical field of surface engineering, in particular to an alkali solution treatment method for improving frictional wear performance of metallic glass and application. The method comprises the following steps: (1) pretreating the surface of a metal glass sample; (2) soaking a metal glass sample in the alkaline solution; (3) after the metal glass sample is soaked, the metal glass sample is taken out and washed; and (4) after washing is completed, putting the metal glass sample into an ultrasonic cleaning machine for cleaning. The metal glass is soaked in the sodium hydroxide solution to form hydride in the metal glass, so that the system is more disordered, the energy is improved, the surface rejuvenation of the metal glass is realized, and the frictional wear performance of the surface of the metal glass is further improved. Compared with other mechanical methods, the method is simple to operate and good in process controllability, and the effect is obviously improved. 本发明涉及表面工程
