The Study on 1Cr18Ni9Ti and 2Cr13 Steel Welding Joints Corrosion Resistance Properties

Abstract:

By method of TIG, and under certain welding craft conditions,1Cr18Ni9Ti and 2Cr13 were welded. By (ZEISS) OM,SEM,the microstructure of two kinds of 2Cr13 and 1Cr18Ni9Ti welding joints were observed and analyzed, Through seawater immersion test, polarization curves and AC impedance spectroscopy of 1Cr18Ni9Ti and 2Cr13 welding joints were obtained. The results show that 2Cr13 and 1Cr18Ni9Ti welded joints is typical columnar crystal, the microstructure is lath martensite + austenite + carbide; polarization curves and AC impedance spectroscopy show that corrosion resistance of welding joint from strong to weak is: austenite base metal>HAZ near austenite>welded joint>HAZ near martensite>martensite base metal; corrosion resistance of welded joint is between martensite base metal and austenite base metal.
