“…The effect of lubricating oil on the pitting was mainly lubrication, and the effect on delamination was impact damage. (4). The thicknesses of the plastic deformation layer were 22 μm, 34 μm, and 40 μm with the quenching temperatures of 900, 1000, and 1100 °C, respectively.…”

“…Surface damage is a very complex phenomenon and the contact fatigue plays a fundamental role in the damage process [1]. The fatigue damages are influenced by various factors, including the lubrication oil, surface roughness, and mechanical properties of materials [2][3][4][5]. Numerous studies have focused on different heat treatment processes to improve mechanical properties in Fe-based alloys [6,7].…”

17Cr2Ni2MoVNb steel is a new type of gear steel in the automotive industry; the rolling contact fatigue behavior is not well documented. In this study, some microscopic analysis methods (optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffractometer (XRD), and energy dispersive X-ray analysis (EDS)) were used to characterize material microstructure and damage surface. In addition, rolling contact fatigue behavior was evaluated by Weibull curve. The results show that the size of austenite grain increased while the quenching temperature increased. Moreover, the samples with a quenching temperature of 1000 °C exhibited the maximum mean life of 7.33 × 105 cycles. In addition, the failure mode of quenched at 900 °C and 1100 °C were delamination, and pitting was the main failure mode of 1000 °C.

“…Austempering is the most widelyused heat treatment procedure to reach excellent combination of high strength, ductility, good wear resistance and tribo-fatigue behavior. So called austempered ductile irons (ADI) in addition to low manufacturing cost, fluidity, recyclability, damping capacity, and heat conductivity are much better than of some grades of alloyed cast steels, consequently they can be considered as an economical replacement for alloyed steel and other grades of cast irons [3,6,7].…”

This research presents the results of tribo-fatigue behavior of austempered ductile cast iron MoNiCa and gives a comparison with standard grades of steel and cast iron. Due to the possibility to combine the castability of cast iron and toughness of steel in one material, new structural material MoNiCa attracted attention of industry and science because of economic benefits and high performance at the different application areas. After successful former experiments the main directions of further development of research for solving relevant practical wear and fatigue problems in rail-wheel system were framed. The complex experimental studies have demonstrated that MoNiCa is consistent with heat treated steels including the rail steels: required tensile strength of rail steel ranges from 1180 MPa to 1280 MPa when rolling surface hardness have to be from 38 HRC to 44 HRC whereas new structural material showed higher tensile strength up to 1400 MPa and slightly higher hardness up to 50 HRC. Herewith the workability of frictional couple cast iron MoNiCa/steel 20MnCr5G exceeds work performance of steel/steel system by 14 %.
