Title: Surface treatment of stainless steel member
Inventor: SHIMIZU SHIGEO
IPC: C23C8/14
Filed: 1992-04-13
Abstract: PURPOSE:To substantially reduce the quantity of eluted impurities by heat- treating a stainless steel member having a specific surface-roughness at specific temperatures for a specific time in a dry oxygen atmosphere incorporating the specific quantity of ozone. CONSTITUTION:The stainless steel member ground so as to keep the surface- roughness to be <=1mum is heated for the oxidation treatment at the temperature range of 150 to 300 deg.C for 1 to 10 hours in a dry oxygen atmosphere to form an oxydized film on the surface of the stainless steel member. Since the oxidizing/removing action of the impurities stuck on the surface of the member is performed by ozone and simultaneously the device oxidized film is formed on the surface of the member at a low temp., the quantity of the impurities eluted from the surface of the member is substantially reduced.
