一种新工艺制造的WC钢结硬质合金经880℃×2h+740℃×8h退火,1150℃淬火后,采用不同回火工艺,通过耐磨性实验进行对比,结果表明150℃×3h回火试样具有最优的耐磨性。
A new process of WC steel cemented carbide after 880 ℃ × 2h + 740 ℃ × 8h annealing, 1150 ℃ quenching, the use of different tempering process, through the comparison of wear resistance test results show that the 150 ℃ × 3h tempering test Like the best wear resistance.
