Correlating Microstructure and Corrosion Properties of Martensitic Stainless Steel

摘要

Martensitic stainless steels(MSS's)are widely used as structural engineering materials, including as tool steels in manufacturing processes such as plastic molding. For these applications, the material must have high hardness, good wear resistance, and sufficient corrosion resistance. The mechanical and microstructural properties of MSS's have, of course, been extensively studied; however, correlation of these to corrosion behavior has not been studied to the extent where a strong correlative understanding exists between microstructural constituents and the thermodynamics and kinetics of local electrochemical phenomena.
