PURPOSE: A shape and structure of a short runner with improved wear resistance, and a surface processing method thereof are provided to implement not only effective and continuous wear resistance but also excellent suitability especially for a tool with a thin wall. CONSTITUTION: A surface processing method of a shape and structure of a short runner with improved wear resistance comprises the following steps. A metal object to be processed is provided. The metal object is coated through a vapor deposition process on a predetermined position. The coating is implemented by a coating substance which is selected from a group composed of a carbide, a nitride, an oxide, and a mixture of the carbide, the nitride, and the oxide. The coating substance is a substance which is selected from a group which is composed of a titanium carbide, a titanium nitride, a titanium bromide, a vanadium carbide, a chromium carbide, an aluminum oxide, a silicon nitride, titanium, a titanium-aluminum nitride, and an aluminum-chrome nitride; and any one between the nitride and the carbide from the same substances of the group. |
