| titleOfInvention | Iron group metal material after black surface treatment and manufacturing method thereof |
| abstract | The present invention provides an iron group metal material after black surface treatment, which forms a black film that has excellent corrosion resistance and sliding performance and does not contain chromium. The surface of the iron group metal material is provided with the following components: a ferroferric oxide layer which is formed through chemical conversion treatment; a chemical conversion treatment layer which is formed on the ferroferric oxide layer and comprises at least one component selected from the following matters: phosphate of at least one element selected from zinc, tin, iron, manganese and calcium; oxide of at least one element selected from titanium, zirconium, hafnium, indium, tin, bismuth, vanadium, nickel, cerium, molybdenum and wolfram; fluoride of at least one element selected from titanium, zirconium, hafnium, indium, tin, bismuth, vanadium, nickel, cerium, molybdenum and wolfram; and a solid lubrication layer which is formed on the chemical conversion treatment layer. |
