Abstract

The invention discloses a titanium alloy TA15 ball head machining and vacuum heat treatment method which comprises the following steps: turning an end surface and a spherical surface of a titanium alloy material, and drilling to obtain a ball blank; grinding the spherical surface of the ball blank; performing ultrasonic cleaning; alpha heat treatment; turning two end surfaces, boring, deburring, grinding and polishing; and after ultrasonic cleaning is conducted, ultrasonic cleaning is conducted again after milling is conducted, and preparation of the titanium alloy ball head is completed. After the titanium alloy ball blank is processed through the alpha heat treatment process, the titanium alloy ball blank is subjected to heat treatment in a certain vacuum state and at a specific temperature, hard titanium oxide is formed on the surface of the titanium alloy ball blank, the surface hardness of the titanium alloy ball blank can be enhanced, and the hardness and wear resistance of the enhanced surface are improved.
