Method for modifying titanium surface through slow-rotating-speed stirring friction machining and method for preparing wear-resistant titanium surface through slow-rotating-speed stirring friction machining

The invention discloses a method for modifying a titanium surface through slow-rotating-speed stirring friction machining. The method comprises the following step that under an argon protection condition, a titanium plate to be treated is fixed to the stirring friction machining equipment for surface treatment, wherein the treatment technology condition is characterized in that the rotating speedof a stirring head is 100-200 rpm, the advancing speed of the stirring head is 10-50 mm/min, and the rolling reduction is 0.1-0.5mm. The invention further discloses a method for preparing a wear-resistant titanium surface through slow-rotating-speed stirring friction machining. The method comprises the following steps that stirring friction machining is carried out by adopting the method for modifying the titanium surface through slow-rotating-speed stirring friction machining, and then surface cutting treatment is carried out, wherein the cutting thickness is 0.8mm-1.5mm. According to the method for modifying the tit
