ABSTRACT:
A method for induction hard-facing, wherein a powder charge is applied to the surface of an item; the item with the powder charge thereon is heated in the electromagnetic field of an inductor until melted to form a hard alloy and a slag, said molten hard alloy being acted upon through the slag layer by a tool carrying on its surface peaks and valleys to form an item with peaks built of hard structural components and of valleys containing plastic components of the melt; the item is then cooled and the action of the tool continued until the hard alloy solidifies completely.
