Abstract
The present invention relates to a material for producing parts or coatings adapted for highly wear and friction intensive applications, said material comprising preformed hard material particles made of carbides which are randomly embedded in a matrix of a host material. In order to provide a material that is suitable to produce parts or coatings having a high wear resistance, and which at the same time causes a low friction resistance, it is suggested that the carbide particles are preformed spherical particles having a hardness in the range between 1000 and 2000 HV/10 and said host material is a Ni based alloy additionally comprising C, Cr, Mo, Fe, Si, B and Cu in the following ranges (in wt %): C 0.005-1.0; Cr 10.0-26.0; Mo 8.0-22.0; Fe 0.1-10.0; Si 3.0-9.0; B 1.0-5.0; Cu 0.1-5.0.
