ABSTRACT:
A support containing iron as a major constituent is plasma-treated in an Ar-gas atmosphere containing carbon gas, to form a region on the main surface of the support. This region contains carbon at a high concentration. A plasma is generated in an Si- and N-containing gas atmosphere, to form an SiN ceramic layer on the main surface. The ceramic layer is placed contact with a rich carbon region on the surface of the support. The ceramic layer is firmly adhered to the support, by means of this region.
