Abstract

The surface of 1Cr5Mo heatresistant steel welding joint was processed with CO2 laser and the corrosion behaviors before and after laser heat treatment LHT were investigated in the salt spray corrosion environments The microstructures phases residual stresses and retained austenite content of 1Cr5Mo steel welding joint before and after LHT were analyzed with optical microscope and Xray diffraction respectively The cracking morphologies and chemical compositions of corrosion products after salt spray corrosion were analyzed with field emission scanning electron microscopy FESEM and energy disperse spectroscopy EDS respectively the polarization curves were measured on a PS268A type electrochemical workstation and the mechanism of corrosion resistance by LHT was investigated as well The results show that the passive film of original sample is destroyed owing to the corrosive media penetrating into the subsurface resulting in the redox reaction The content of residual austenite in the surface and the selfcorrosion potential are increased by LHT which is contributed to improving the capability of salt spray corrosion resistance
