Abstract

Application of low alloy steel in the wood processing in pulp and p per mills is widely used due to its strength and ease of forming. However, Low wear resistance due to friction makes the service life short and thus uneconomical. Increasing the wear resistance of the surface by hard-facing is an attractive solution and easy to implement. This study aims to evaluate the effectiveness of hard-facing welding in improving wear resistance, hardness, and observe the microstructure. Hard-facing process is carried out by SMAW (Shielded metal arc welding), AWS (American welding Society) e Fe Cr-a1 electrode 4 mm diameter, current (170, 175, 180, 185, 190 A) polarity DC+ welding position 1G and consists of 1 layer. The increase in specific wear resistance from the OAT-U Universal Wear Tester test results and the increase in surface hardness are proportional after hard-facing. In this study, Specific wear and surface hardness of the specimens were found to be better with SMAW welding at 185 A. The specific wear (Ws) of the specimen after Hard-facing SMAW 185A is 0.000382 mm2/kg, surface hardness 476 Hv. Before hard-facing, the specific wear value was 0.002146 mm2/kg and the surface hardness was 96 Hv. The specific wear resistance increased by 5.6 times and the surface hardness by 4.95 times.
