凿工

Increasing quenching temperature can improve the impact toughness and wear property, and the optimal impact toughness (40 J/cm^2) and wear performance of the tested steel can be obtaind by quenching at 1100℃ and tempering at 250℃ SEM analysis finds that the main wear mechanism is cutting wear and fillister under the low stress grinding abrasion.

提高淬火温度有利于冲击韧度和耐磨性的提高，经1100℃淬火＋250℃回火热处理，材料可获得最佳的冲击韧度(40J/平方公分)及耐磨性。用SEM分析发现，在该低应力磨料磨损工况下，实验钢的磨损形式主要有显微切削和凿坑。
