On the Corrosibility and Passivity Formation of Silchrome Steel of various Microstrucutres

Abstract

By the heat-treatment of silchrome steel, the author obtained various microstructures, such as austenite, martensite, troostite, sorbite and spherical pearlite, and also the corrosibility and passivity formation of these microstructures in sulphuric acid and ferricsulphate solution were studied. By this investigation the critical concentration of ferricsulphate for inducing passivity of these microstructures was determined.
