The durability of heat-resistant metal (Fe based alloy and Ni based alloy) and surface-modified materials (spraying, calorizing) were evaluated by oxidation tests at high temperature achieved by the combustion of natural gas in order to determine which metal was superior in durability and economic efficiency. In the result, it was found that the most durable and useful material was the SUS 310 S with CoNiCrAlY coated by HVOF.
