is occurred encroachment and erosion by molten metal attacks. Coating
of tungsten carbide or particular Cermet electrodes can provide the layer
which is harder high temperature hardness and uneasily to react with molten
metal. As the result, the dies are prevented from erosion, scuffing, and
heat-cracks, and given longer lives. And also, improve release properties,
liquid flow, and gas release as well as product quality. |
