Date Dec. 23, 1982.A method of enhancing the corrosion resistance of sintered stainless steel, particularly against attack by acids, such as acetic acid, under non-oxidizing conditions. The sintered stainless steel is activated, for example by treatment with acid and is then treated with a phosphate containing solution. The sintered stainless steel has improved resistance to subsequent attack by acid. |
