METHOD FOR THE PRODUCTION OF A HEAT RESISTANT ALLOY WITH GOOD RESISTANCE TO HIGH-TEMERATURE OXIDATION

摘要

The invention relates to a method for the production of an alloy, with hightemperature oxidation resistance and high heat resistance, which comprisescoating a base material made from an austenitic, heat resistant nickel-basedalloy, or cobalt-based alloy or stainless steel, with high plasticity. Saidcoating is a layer of aluminium or an aluminium alloy applied on one or bothsides. The composite material formed as above, from base material and analuminium coating with good adhesion, is brought to the final dimensionsthereof, by forming with or without intermediate annealing.
