<p>A method for forming a Re-Cr alloy coating film through electroplating, wherein a Re-Cr alloy coating film containing Re in an amount of 60 to 90 atomic % and Cr and inevitable impurities in the balanced amount is formed by the use of an electrolytic plating bath comprising an aqueous solution containing a perrhenate ion and a chromium (IV) ion. The formation of a coating film of a Re-Cr alloy being used as a corrosion-resistant alloy coating film for a member of a high temperature device through an electroplating using an aqueous solution has allowed the impartation of high heat resistance and corrosion resistance also to a member of a device having a complicated shape, with ease and at a low cost.</p> |
