Abstract

If hard layers could be formed with the electric discharge machines (EDM) now popularly used for material removal, the time and cost of producing dies and machine parts would be greatly reduced. The wear properties of hard layers formed on stainless steel using EDM were studied. As a result, it was found that the hard layers formed with TiH₂ green compact electrodes are three to four times more wear resistant and the layers formed with TiC semi-sintered electrodes are about 10 times more wear resistant than surfaces with no hard layer.
