Hardness design of anti-wear components in agricultural machinery

The failure form of agricultural machinery anti-wear components is mainly abrasive and adhesive wear. Based on the concerned wear characteristics research work of the wear resistance components, the effect of hardness and other mechanical properties of steel on the abrasive and adhesive wear resistance of the wear resistance components was discussed in this paper. The special attention was paid on the contradiction between toughness and wear resistance for impact abrasive wear components. With certain components, the hardness design were made and the good combination of toughness and wear characteristics were obtained.
