High Temperature Bearing Steel and Anti-Corrosion Bearing Steel

In this study, attempt has been made to investigate the effect of SiC particles on the friction and wear properties of Ni/SiC composites manufactured by electrodeposition, especially for the composites with high-temperature treatment.For this purpose, α-Al2O3 was coated on the surfaces of SiC particles by sol-gel technology to inhibit interfacial reaction of SiC and nickel at high temperature. Both of the Ni/α-Al2O3-coated SiC (Ni/CSp) and Ni/uncoated SiC (Ni/UCSp) composites were treated at 600 °C to study the resulting wear behaviour. The results indicated that with heat treatment at 600 °C, the Ni/CSp composite had better tribological properties than the Ni/UCSp composite. It was proved that the uncoated SiC particles have reacted completely with nickel leaving many defects, while the coated SiC particles still remained in the Ni/CSp composite hardening the nickel matrix and supporting the counterpart, thus improving the wear resistance of Ni/CSp composite with relatively low friction coefficient and wear mass loss compared to the Ni/UCSp composite.

In this study, two different AISI 52100 bearing and D2 tool steels were subjected to ultrasonic nanocrystalline surface modification (UNSM) technique at ambient and high temperature of 500 °C. The objective of this study is to characterize the microstructure and to investigate the effectiveness of UNSM technique on the friction and wear behavior of those steels. The friction and wear behavior of the specimens against AISI52100 bearing steel ball with a diameter of 10 mm was carried out using a micro-tribo tester under dry conditions. The hardness with respect to depth from the top surface was measured using a microhardness. The change in the microstructure of the specimens before and after UNSM treatment was characterized by scanning electron microscopy (SEM). The findings from this preliminary study are expected to be implemented to the bearings and tools to increase the efficiency and performance of the components.

Background:: The Cr4Mo4V steel is widely used in high temperature bearings because of its excellent high temperature performance. According to the research status of Cr4Mo4V at home and abroad, this paper explores its mechanical properties and friction properties at high temperatures. Objective:: To characterize the composition, microstructure and properties of Cr4Mo4V steel and to explore its tensile properties, hardness and friction properties at high temperature. Methods: Many methods are adopted, such as chemical element analysis, metallographic analysis, hardness test, tensile test, damping test, friction test and so on. Results: The microstructure of Cr4Mo4V is tempered martensite. The hardness and maximum tensile strength of Cr4Mo4V decrease with temperature increasing. The grain of the Cr4Mo4V steel after heating gets refined and the grain boundary increases. At room temperature, the surface friction coefficient and wear rate of Cr4Mo4V steel decreases. Moreover, Cr4Mo4V steel-ceramic ball shows the best friction resistance. At high temperature, the friction coefficient and the wear of Cr4Mo4V steel firstly decrease with temperature increasing and then increase sharply at 200°C. Conclusion: With the increase of temperature, the hardness, breaking force and tensile strength of Cr4Mo4V bearing steel decrease, whereas the friction property increases. By analyzing the three-dimensional morphology of different wear samples, the optimal working temperature of Cr4Mo4V steel for bearing is 200°C.
