Abstract
The wear resistibility of gray cast iron HT200 is improved by employing inert gas tungsten arc remelting and fast solidified, the effect of current and arc moving rate on the chilling layer properties are studied. And it is compared with laser hardening. The results show that Tungsten inert Gas Arc remelting can improve the resistance to abrasion of cast iron and it is much better and cheaper technique than others.
