Title:
MANUFACTURE OF DRY TIN PLATED STAINLESS STEEL FOR DECORATION
Document Type and Number:
Japanese Patent JPH0525636
Kind Code:
A
Abstract:

PURPOSE: To manufacture a dry TiN plated stainless steel excellent in adhesion of films and corrosion resistance and having a beautiful gold color on the surface by a vapor phase deposition method.

CONSTITUTION: An austenitic stainless steel contg., by weight, 12.0 to 35.0% Cr, 7.0 to 50.0% Ni, 0.01 to 0.03% C, 0.01 to 2.00% Ti and 0.1 to 5.0% Si and furthermore contg., at need, ≤0.3% N is used as a base metal. The surface of the above stainless steel is vapor deposited with a TiN film having 0.1 to 5.0μm thickness, and it is subjected to heat treatment of holding in the temp. range of 500 to 1150°C for ≥0.5min in a nonoxidizing atmosphere with -15 to -55°C dew point. The space between the stainless steel and the TiN film may be vapor-deposited with a Ti film as well as the content of N may gradually be increased in the TiN film from the side of the Ti film to the surface and the thickness of the Ti film is regulated to 0.03 to 2.0μm.
