The invention discloses a method of utilizing a tool dedicated for a steel ball chemical heat treatment to modify the surface of a steel ball, and relates to a steel ball surface modification method.The invention aims to solve the problems that when a conventional tool is used to modified steel balls, the steel balls are densely arranged, the air flowing is influenced, the contact area between the steel balls and the tool is too large, the infiltrated layer becomes non-uniform, and the infiltrated layers of steel balls of one batch are uneven. The method comprises following steps: step one, using a steel material processing knife edge type support; step two, assembling a tool dedicated for a steel ball chemical heat treatment; step three, placing a plurality of steel balls on the tool; and step four, utilizing a surface modification facility to carry out surface modification on the steel balls on the tool to obtain steel balls with modified surfaces. The method is suitable for steel ball surface modification.
