| Abstract | ||
| This work was carried out to invistigate the plow shear wearing resistance under different heat treatments; dry heat at 84 °C for 210 min, cooling by air and cooling by water. Three different Plow shares a , b and c with different HRC Recal hardness number, cooling by water at 60°C, cooling by air at 40°C and control at 36°C HRC . The experiment was conducted in a sandy loam soil with 12 % moisture content. The study revealed that wearing rate was lower for share A comparing with B and C. The resultes further showed that wearing rate increased with the treatment A reaching 4.1 km g-1 in comparison to tratment B which was cooled by air. The hardness of treatment B increased to 39.5 rockwell and the wearing rate decreased by 1.3% (0.6 g km-1). The wearing resistance of the same treatment was 1.81 km g-1. The control treatment (C) demonstrated the lowest values for both hardness of 36 rockwell and wearing resistance of 1.1 kg/g. It also showed the lowest value of 2.1 for the wearing rate. | ||
