| Abstract: | A more comprehensiv investigation is carried out for the har-dened layers of several common carbon steels(45#,T8A,T12A)by solar energy surface transformation hardening.The measurement of hardness,surface residual stress,subgrain size,and content of surface retained austenite are presented,and also the wear and corrosion resistance of the hardened layers are studied.The hardened layers by solar energy hardening show some distinctive and superior characteristics:the hardness,the content of surface retained auste-nite,and the microstrain within the crystals of the whole hardened layer are higher than those hardened by means of conventional met-hods;the subgrais size was obviously fined;on the two directions of hardened bands there are different kinds of surface residual stress;the wear and corrosion resistance are greatly improved. |
