| Abstract: | This paper deals with the microstructure and wearability of boron cast iron after laser heat-treatment. The results show that the microstructure of laser hardding consists of martensite,spheroidal and flake carbide and retained austenites. This structure has good pop-erty. The wearability of the boron casst iron increases by a factor of 6. |
