摘要：
Additions of 1-5 wt% W element enhanced corrosion resistance and mechanical properties of LDED-316 SS. Microstructure characterized the grain refinement and precipitation of ferrite and W -Mo carbides. Mechanical tests showed enhanced tensile strength and hardness of 316-5 W by 37.4% and 30.8%, respectively. Electrochemical tests indicated an increasing pitting potential and polarization resistance of 316-3 W in 3.5 wt% NaCl solution by 0.535 V & Oslash; and 1679 k Omega & sdot; cm 2 , respectively. Corrosion morphology showed the preferential dissolution of ferrite and W -Mo carbides rather than austenite cell. The change in corrosion processes and presence of WO 3 in the passivation film significantly contributed corrosion resistance.
