Abstract
Die wear is an important problem for manufacturers in hot-working processes, e.g. metal die casting, hot extrusion and thixoextrusion of aluminium, magnesium or steel, as well as glass and plastics processing. The dies have to be capable of withstanding complex thermal and mechanical loads, while giving a sufficient wear resistance against abrasiorband adhesion at very high temperatures. In order to improve the wear resistance and reduce the heating of the extrusion die it can be protected with ...
