IMPROVEMENT THE MECHANICAL WEAR RESISTANCE OF METAL KNIFE USED IN HARVESTER MACHINE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 10
Abstract
The fast wearing components of agricultural machinery requires replacement which effect on the work as well as the quality of equipment. A special verification of possible heat treatment (H.T) carburizing and mechanical treatment (M.T) shoot peening of steel were Responded applied on carbon steel type (AISI 1030), have been done with view of conditions of real mechanical abrasive wear of harvester machine. These techniques are found promising to enhancement the quality of harvester knife, which is manufacturing in Iraq. Mechanical wear resistance is very important in many applications and in most cases it is directly correlated with metallurgical and hardness of materials surface. After both surface treatment (H.T and M.T) were applied the mechanical wear by using harvest process to determine the (actual wear rate) of the specimens depending on weight loss method. The results were found as; (1) the wear resistance Increases with increase hardness with varying surface treatment as follows; 35HRC, 47HRC, 55 HRC and 58 HRC for specimen’s as-received, (2) increase wear resistance with increase shoot peening time at 30 min to 45 min respectively: (3) We found the fine of grain size structure in case of (M.T) shoot peening treatment. (4) The surface wear appearance were presented on the worn surfaces of the steels depended on type of treatment surface
