Rod for coating machine and method for producing the same

摘要

A rod for a coating machine according to the present invention includes a cylindrical base material, an intermediate layer formed on the surface of the base material and subjected to a lapping process and an abrasion-resistant film formed on the surface of the intermediate layer and subjected to a lapping process. The intermediate layer is a diffusion layer formed by reforming the surface of the base material by a diffusion process. Specifically, since the intermediate layer forms a part of the base material, the intermediate layer is firmly fixed to the base material and is not likely to separate from the base material. According to the present invention, a rod for a coating machine with high durability and a method for producing it are provided, which rod prevent flaws from developing on the surface of a base material object on which a coating solution is applied.
