Corrosion-resistant member production method and laser cvd device

Abstract

Provided are: a method for producing a corrosion-resistant member, wherein the method enables the formation of an anodized aluminum coating with the occurrence of burning due to irradiation with laser light prevented in spite of the inclusion of aluminum or an aluminum alloy as a substrate; and a laser CVD device to be used for obtaining this. They are: a method for producing a corrosion-resistant member, the method comprising: a coating formation step of forming an yttria coating on a surface of a substrate consisting of aluminum or an aluminum alloy by irradiating the substrate with laser light while the substrate is blown with a raw material gas containing yttrium, wherein the laser light is in the form of a pulse wave, and the substrate is allowed to have a temperature of 300° C. to 600° C. in deposition for forming an yttria coating; and a laser CVD device to be used in this method.
