      • Abstract
    • Surface welding material was treated by tungsten inert gas (TIG) surface remelting process for its modification.Compared with grinding process,the effect of TIG surface remelting process on cavitation corrosion resistance was investigated.After 45h of cavitation corrosin test,the mass loss of the specimen with ground surface was 1.57 times that of the specimen with TIG remelted surface.The fracture of martensite transformed by austenite was the main form of mass loss.TIG surface remelting process put off the transformation-saturated point and decreased mass loss.TIG remelting process repressed crack growth and avoided the falling off of big particles.
