According to ASTM A967, passivation is the chemical treatment of stainless steel with an oxidant agent, to remove free iron or other materials. The passivation baths commonly use citric and nitric acid as oxidizing agents. However, the latter generates toxic vapors that are harmful to health [22,23,24]. On the other hand, citric acid is ...

ASTM A967 defines seven tests for verification that a suitable passive surface has been formed on the component surface. These tests are all qualitative. Although some tests can more precisely detect the amount of free iron remaining on a surface, they are meant to serve as a go, no-go test for passivation. Water immersion test.

Materials used in this investigation were SS 304, 15-5PH, and 17-4PH whose chemical composition was determined by X-ray fluorescence. Preparation of the electrodes: each of the SS was prepared according to ASTM A380 [] in order to obtain a surface without harshness, after which a washing and rinsing was carried out to eliminate preparation …

35A, AMS 2700C, ASTM A 967-05 and ASTM A 380-06 standards. Passivation alone will not remove heavy adherent oxide films created from heat treatment, welding, hot-forming and other high-temperature operations. Therefore AST uses different types of pickling acids designed to remove these films prior to the Passivation of the parts.
