Abstract (en)

[origin: EP0554682A1] A description is given of a process for impregnating or embedding hard, wear-resistant phases in surface layers of metal products made by casting liquid metal. Said process is intended to permit "mechanical" adhesion of the wear-resistant layer on the cast surface. It is proposed to produce a wear-resistant layer in the form of a thin disc or plate, on the one surface of which at least one protruding pin or anchor adheres. The disc or plate is fixed on a surface of the mould before casting the metal. <IMAGE>
