Abstract
PURPOSE:To form a covering layer with superior high temp. strength, corrosion resistance and oxidation resistance on the surface of a heat resistant alloy by covering the surface with Ni and a Pt group metal in order followed by diffusion covering of Al. CONSTITUTION:The surface of a heat resistant alloy based on at least one of Fe, Ni and Co is plated with Ni and a Pt group metal such as Pt, Rh or Pd in order. The plated alloy is then buried in a pack material consisting of 200 mesh Al powder 30 wt%, 325 mesh Al2O3 powder 69 wt% and NH4Cl powder 1 wt%, and it is heated to 800 deg.C for 2 hr under an Ar gas atmosphere to be subjected to Al pack treatment. A covering layer made of intermetallic cpd. of the Pt group metal and Al is formed on the alloy surface, and a NiAl layer contg. little undissolved precipitated particles or carbide is formed under the above layer, thus remarkably enhancing the thermal impact resistance of the covering layer.
