PURPOSE:To obtain a structural material for a high temp. furnace having improved heat resistance and a prolonged life by coating the surface of an Mo-base structural material with a thin TiC layer. CONSTITUTION:A structural material 2 made of Mo or an Mo alloy is placed in a vapor phase plating furnace 1 kept at about 1,000 deg.C high temp., and a gaseous mixture 3 consisting of TiCl4, N2 and H2 is fed to form a thin TiC layer 4 of about 5-50mum thickness on the surface of the structural material 2. A structural material for a high temp. furnace preventing loss on heating and reduction in the thickness due to the falling of the surface layer can be provided. The structural material has a long life. |
