| Abstract: | The crack morphology of hardfacing metal was investigated by means of optical and scanning electron microscopy. The effect of RE oxide on cracking resistance of hardfacing metal was studied. The results show that the main forms of cracks in hardfacing metal are primary crystallization crack and quench harding crack. The cracking resistance of hardfacing metal can be improved by adding RE oxide in coat of electrode. |
