چکیده مقاله
To increase the hardness and wearing resistance as well as to create a crack free clad on the ductile cast iron, two layers of clad via shielded metal arc welding SMAW process by using E 316L, E NiCr and E HS60V electrodes were weleded on substrate and the effect of chemical composition and sequence of cladding layers on the microstructure and quality of clad were investigated Microstructural and XRD phase analysisng illustrated that the use of E 316L and E NiCr electrodes result in formation of austenitic clad layer Forthermore, E HS60V electrode caused formation of chromium rich carbides in the clad layer The microhardness test revealed that the formed clad layer via E 316L for first layer and E HS60V for second layer result in formation of the surface clad withhigh hardness and quality crack free This should be noted that due to the more economical aspect of E 316L than E NiC, cladding in the E 316L/ E HS60V sequence is important for the repair and claddding of ductile cast iron in the industiral application
