摘要：
The wear resistance and feasibility of applying soil rippers have been studied after surfacing for use in the clayey soil. The study illustrates laboratory and production research of standard and novel (with large grain tungsten carbide) material for manual electric arc surfacing. Hardness and wear resistance in the clayey soil have been determined. Rippers (and the components of soil cultivating machinery yield the least wear by using wear-resistant materials and the comprehensive surfacing of tailing and lateral surfaces. It is shown that hard-alloy tips of rippers are better suited for clayey soil, which is the toughest to cultivate. The best wear resistance in clayey soil is found in hard-alloyed layers of Fe-C-Cr-Si-Mo-Nb-W and Fe-C-Mn-B alloys. The wear rate depends on the depth of cultivation and varies exponentially.
