| description | PURPOSE:To raise the manufacturing yield of products by enabling good solar energy absorptive film to be formed by a method in which the surface of a steel plate is treated so that a metal element-enriched layer in a reduced state is formed and then subjected to a bright annealing, followed by rust-proofing treatment before a selective absorption film processing. CONSTITUTION:A metal element(in reduced state)-enriched layer is provided on the surface of a stainless steel plate in a thickness of 50Angstrom depth at most. In forming a selective absorption film for solar energy collection, the steel plate is subjected to a bright annealing process under conditions to meet the relationships, 800 |
