ABSTRACT
The influence of silicon carbide SiC abrasive particles of 20, 30, 40, 50 and 60 size on carburized digger tooth steel was studied. Four types of steel, with different hardness, were tested at two constant linear sliding speeds and under various loads of 10, 20, 30, 40 and 50N. Tests were carried out for sliding time of 0.5, 1.0, 1.5, 2.0 and 2.5min. Experimental results showed that there was consistent reduction in abrasive wear as the hardness of the materials was increased. It was found that wear increased with the increase of applied load, linear sliding speed and sliding time. Also, it was noticed that the wear increased with increase in abrasive particle size, and the most effective size was 40 . SEM observations of the worm surface showed that the cutting and ploughing were the dominant abrasive wear mechanisms.
