用いる必要がある。Cleaning or polishing of the surface of these steel plates
It is necessary for the N film to be firmly adhered to the surface of the base steel, and for this purpose it is important to clean the surface of the steel plate. Regarding polishing, it is essential to polish the surface of the material uniformly, and especially when polishing a material with a large surface area, polishing spots become a big problem.
For example, it is necessary to use a jig that prevents the material from flapping during polishing.

For example, in dry plating by CVD method, TiCl a + Nt'+
By using a rotating shower system at multiple locations when introducing a mixed gas (reactive gas) at Hz, the reactant gas can be uniformly introduced onto the surface of the plate material.
By using a large evaporation source (and using a rotating shower system for the N2 gas inlets provided at multiple locations), the ionized Ti and N can uniformly promote the TiN reaction on the surface of the plate material. This makes it possible to form a TiN film uniformly over the entire surface of the material.

In the above case, the cost will increase, so the TiN film is o,
It is desirable to set it as the range of oos - 10 micrometers.
