| Abstract | ||
| In this paper, a study the effect of quenching media on the mechanical properties and abrasive wear has been done on steel blade (34Cr4) for agriculture equipment with soil texture. It has found that heat treatment technique is promising to improve the quality of agriculture equipments and components working in soil under dry conditions. Abrasive wear resistance is very important in many applications and it is directly correlated with hardness of metal surface. The heat treatments have large role to alter the mechanical properties and wear resistance of steel type (34Cr4). It was found that the wear resistance increases with increase hardness which increases with varying quenching media as follows; 38HRC, 56.6 HRC, 58.3 HRC and 60.6 HRC for as – received sample, caustic Soda (10%), engine oil and flaxseed oil respectively. It was found also that the wear resistance increases with decreasing toughness to values 48.3 J, 45 J, 40.2 J and 27J respectively. Wear was presented on the worn surfaces of the steels which were used in this work. All mechanical properties depended on microstructure which consists of martensitic structure and some amount of carbide particles. | ||
