Abstract:The abrasive wear behavior of hypereutectic and hypoeutectic based Fe-Cr-C hardfacing are reported and interpreted in terms of the microstructures. The coating were deposited onto a Mild steel substrate by shielded metal arc welding using two commercial hardfacing electrodes. The abrasive wear tests were conducted using a dry sand/rubber wheel abrasion tester as per procedure A of ASTM G65standards in agricultural implements. It was found that hardness of hypereutectic coating was significantly higher than hypoeutectic coating in both cases optimum hardness was achieved in the results. Hardfacing is one of the most economical ways to increase the wear resistance and the hardness. Wear is predominant factor that service life components of any machine parts. Metal parts usually cannot withstand because of wear. Hardfacing involves the application of deposition of material on the surface of metallic work piece by using welding method such as the electrodes consists of alloying elements such as chromium, manganese, carbon, silicon, phosphorus, sulphur, molybdenum, nickel and vanadium.
