【 摘 要 】

The paper presents the research of the wear intensity of welded layers in natural soil abrasive mass. The samples made of 38GSA steel with the welded surface layers contains carbide forming elements. In case of the test abrasive mass, XHD 6715 material showed the wear 2.5 times lower than El-Hard 61 and twice smaller than El-Hard 65. The analysis of the wear indicates that the welding layer containing vanadium and chromium carbides, molybdenum and niobium carbides has proven to be the most resistant to wear in the test abrasive mass.
