Claims

[Scope of utility model registration request]

(1) This is achieved by coating a shaft core made of steel or other material with a ceramic material, covering the entire circumference or part of the surface, thereby increasing the wear resistance and oxidation resistance of the shaft surface. An industrial shaft featuring:

(2) The industrial shaft according to claim 1, wherein the ceramic material is mechanically fixed by a circumferential shape or a circumferential groove formed on the outer periphery of the shaft core metal.

(3) The scope of the utility model registration claim, characterized in that the ceramic material consists of a large number of embedded elements that are evenly distributed around a part of the entire circumference of the shaft core metal so as to be continuous in the circumferential direction, and are buried in an exposed state. The industrial shaft according to item 1.
