文章研究了具有各种显微组织的普通碳钢的三体磨料磨损抗力。采用含碳0.1~1.2%的碳钢,其碳化物相的体积分数可以在一个很宽的范围内变化着,把每一种碳含量的钢处理成球化组织或层片状组织淬火及回火后,可改变碳化物颗粒大小和颗粒间的距离,等温转变后改变了层间间距。磨损抗力的大小是采用试样在尺寸为50—105μm的细石英粉末进行磨损实验后的重量损失来衡量的。利用光学显微镜和电子显微镜检验磨损痕迹,以阐明三体磨损的机理。表征磨料磨损抗力的大小,既不能完全采用硬度,也不能单纯用组织形态特征;而硬度和韧性的配合是更重要的。
The article studied the wear resistance of three-body abrasive of common carbon steel with various microstructures. The use of carbon steel containing 0.1-1.2% carbon content, the volume fraction of the carbide phase can be varied within a wide range of each of the carbon content of the steel into a ball or flake microstructure of the quenching and processing After the fire, the size of the carbide particles and the distance between the particles can be changed, and the interlayer spacing is changed after the isothermal transformation. The size of the wear resistance is measured by the weight loss of the sample after it is subjected to a wear test on fine quartz powder having a size of 50-105 μm. The wear marks were inspected by optical microscope and electron microscope to clarify the mechanism of three-body wear. Abrasive abrasion resistance characterization of the size, either can not completely use the hardness, can not simply use the organizational features; and hardness and toughness is more important.
