| titleOfInvention | Removal method of chromium compound coating film |
| abstract | (57) [Problem] To provide a coating film made of a chromium compound applied to the surface of a metal substrate without damaging the internal metal substrate. A method of completely removing or stripping is provided. SOLUTION: A member in which a coating film made of a chromium compound such as chromium nitride, carbide or carbonitride is formed on a surface of a metal substrate is treated with an alkaline material having a pH of 7.3 or more, preferably pH 8.5 or more. By immersing in an electrolytic solution and passing a current between the member and the control electrode using the member as an anode, the potential difference between the member and the control electrode is increased by + The chromium compound-coated film is dissolved and removed by controlling the voltage to 0.1 to +1.0 V (to silver-silver chloride electrode). |
