This invention relates to the protection of metallic surfaces susceptible to abrasion by rock-like material. According to the invention, a metallic surface susceptible to abrasion by rock-like material is protected by stud welding studs of abrasion resistant metallic material to the metallic surface in closely spaced relationship to cause the majority of the rock-like material to contact the abrasion resistant studs instead of the metallic surface. Typical of such metallic surfaces are a ground engaging tool, earth-working equipment, or chutes for conveying the rock-like material. The abrasion resistant metallic material comprising the stud can be formed of cast material of compacted metallic powder. |
