Abstract:
1. A method of producing a wear part or tool comprising a body containing an iron-group metal or alloy, a wear-resistant layer metallurgically bonded to a surface of the body through an intermediate layer, wherein the wear-resistant layer comprises at least 13 vol. % of grains of metal carbide selected from the group consisting of WC, TiC, VC, ZrC, NbC, Mo2C, HfC and TaC and grains of (Cr,Me)xCy, where x and y are variables, with variable y being either 3 or 6 and when variable y is 3 then variable x is 7, and when variable y is 6 then variable x is 23, and a metal based phase comprising of a solid solution of 0.5 to 20 wt. % Cr, 0.2 to 15% wt. Si, and 0.2 to 20 wt. % carbon, where Me is Fe, Co and/or Ni including the steps of: providing a body formed of an iron group metal or alloy, providing a composition of grains of a metal carbide and the components for a metal based phase comprising an iron-group metal, silicon and Cr applying a layer of the composition to a surface of the body, forming the intermediate layer and the wear-resistant layer at the same time by:
