| titleOfInvention | Method for passivating stainless steel product and method for producing stainless steel separator for fuel cell |
| abstract | A method for passivating stainless steel product, which comprises immersing a press-formed material (11) in a treating solution (12) having a temperature of 40 to 60°C and a pH of 9 to 12, to form a passivated coating film (26) on the surface of the material, or alternatively which comprises carrying out degreasing, washing and the passivation treatment using the above treating solution by means of a spraying method. The passivation treatment by the method is free from the elution of a metal ion from the material and allows the achievement of passivation by the use of a single treating solution, resulting in the reduction of a passivation cost including a waste treatment cost, and the latter method allows degreasing, washing and a passivation treatment to be speeded and to be practiced with a reduced amount of treating solutions, due to the employment of a splaying process. |
