Abstract

Wear is a serious problem in the components of machinery, particularly those used in the mixing and crushing of soil, cement, glass, bricks, etc. Excessive wear causes a consequential increase in the costs of production and maintenance for the firms involved in this type of business. Various wear resistant materials used in industry are seen in Table 1. White iron castings are generally regarded as a good selection for many applications to minimize the wear problem. The present work describes studies on developing a wear resistant material with low wear rate per unit cost. The scrap of X210Cr12 high carbon, high alloy tool steel was remelted and cast in ingot form by using an induction furnace under vacuum conditions and hypoeutectic white cast iron was produced. Some of material was then exposed to a quenching and tempering heat treatment. Wear resistance and toughness tests of specimens yielded better results for quenched and tempered condition of white cast iron. In impact tests the impact energy of quenched and non-quenched specimens was found to be 0.3 kgf.m and 0.2 kgf.m respectively. It was also determined that a decrease in the relative wear rate per unit cost of quenched and tempered specimens in 35% was maintained with respect to other wear resistant materials.
