Abstract: The invention relates to a wear-resistant roller for crushing of particulate material, such as crude ore for use in the cement or minerals industry comprising a roller body, a wear surface on the roller body. The wear surface comprises welding beads comprising a primary fraction of carbide material and a secondary fraction of material selected from the group consisting of Nickel, Nickel alloys, mixtures of Nickel and Nickel alloys and mixtures of Nickel containing refractory hard materials, Cobalt, Cobalt alloys, mixtures of Cobalt and Cobalt alloys and mixtures of Cobalt containing refractory hard materials. Furthermore, the welding beads are welded to the roller body in an overlapping manner such that two neighbouring welding beads comprise an overlapping volume and a non-overlapping volume, the overlapping volume being an intersection volume between the two neighbouring overlapping welding beads, and the fraction of carbide material being higher in the overlapping volume than in the non-overlapping volume such that the overlapping volume has a higher wear resistance compared to the non-overlapping volume having a lower wear-resistance. Also the invention relates to a method of forming such a wear surface on a roller body.
