Abstract
The invention relates to 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, characterized in that 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, MoC, HfC and TaC and grains of (Cr,Me)Cand a metal based phase comprising of a solid solution of 0.5 to 20% Cr, 0.2 to 15% Si, and 0.2 to 20% carbon, where Me is Fe, Co and/or Ni; and the intermediate layer has a thickness of 0.05 to 1 mm and comprises Si in amount of 0.1 to 0.7 of that in the wear-resistant layer, chromium in amount of 0.1 to 0.6 of that in the wear-resistant layer and the metal of the metal carbide in amount of 0.2 to 0.6 of that in the wear-resistant layer and to a method of producing such a wear part.
