Abstract

The effects of the hot stamping process and different hardfacing techniques, such as shielded metal arc welding (SMAW) and gas metal arc welding (GMAW), on the abrasive wear of ploughshares were investigated under field operational conditions. The abrasive wear losses were determined by measuring the weight and dimension changes before and after tillage. The wear losses of hot-stamped and hardfaced ploughshares were less significant than those of the conventionally heat-treated ploughshare specimens used under field conditions. Conventional heat treatment and hardfacing by the SMAW process decreased the wear weight losses by 46.31% and the dimensional losses by 86.77% in comparison to the performance of the conventionally heat-treated ploughshares. These values were 36.90% and 88.17%, respectively, for conventional heat treatment and hardfacing by the GMAW process. There were no statistically significant differences between the SMAW and GMAW hardfacing processes in terms of wear losses. Hot stamping and heat treatment applications on the ploughshare also decreased wear losses by 19.03% and dimension losses by 13.82% in comparison to the conventional heat treatment process. According to the results of the overall study, hot stamping and hardfacing by SMAW and GMAW processes can be recommended as efficient solutions for decreasing the wear losses of ploughshares.
