Abstract
A paint priming method which forms, on the surface part of a ferrous material to be treated, a nitride layer with an adequate depth and preferably .epsilon. phase as a main phase thereof, and with no carbon adhesion to the surface thereof, by carrying out a gas soft nitriding treatment with gas components which generate no free carbon. The nitride layer formed on the surface part of the material is used as a presubstrate on which direct painting is possible, thereby providing a simplified and improved presubstrate treatment for painting.
