Abstract
Electrodischarge machining with pulsing relaxation generator using a p owder compact electrode and reverse polarity setting modifies the surf ace properties of a machined surface greatly. Using a hard and wear-re sistant material in the compact, the wear resistance of the resultant surface can be improved. In the present investigation, tungsten carbid e powder is used in the compact. The wear resistance is evaluated by c utting tests and the results show considerable improvement over the un coated surfaces.
