Abstract (en)
[origin: WO2004005561A2] The invention concerns a method whereby wear and scratch resistance of metals having a reduced hardness is enhanced by embedding in a metal powder, non-oxide ceramic, such as nitrides and carbides, while preserving a metallic shine. The embedding of non-oxide ceramic particles is carried out by combined grinding of the metal powder in a ball-mill (1), followed by compacting and sintering of the resulting material. The metal powder can be sintered either in solid phase or in liquid phase. In order to improve compatibility between the ceramic particles and the metal during the sintering process, the non-oxide ceramic is selected so as to have a density close to that of a soft metal to be reinforced. The cermet composite obtained exhibits a reinforced hardness and a density close to that of the initial metal.
