The primary aim of the present investigation is to evaluate the sliding wear response of M50 steel against three different counter-bodies as function of applied load and sliding velocity. The investigation is essentially undertaken to understand the sliding friction of hybrid bearing and ordinary bearing used in spacecraft and aeroengine. Towards that purpose, M 50 steel was made to slide against three different counter-bodies such as M50 steel, 52100 steel and Si 3 N 4 , at three different applied loads and at three different sliding velocities. The results show that the friction coefficient of M50 steel decreases with the applied load and the sliding velocity against all types of counter-bodies. The wear rate of M50 steel against Si 3 N 4 counter-body increases with the applied load and the sliding velocity. In contrast, the wear rate is generally independent of the applied load and the sliding velocity against 52100 steel and under self-mating condition.

“…Sliding wear is an important degradation mechanism to which bearings and gears are subjected. Sliding wear behavior of several steels is reported in recent times by several investigators [5][6][7][8][9][10]. Sliding wear of M50 steel is also investigated [11][12][13][14].…”

“…Medium-carbon steels are commonly used as tool steels due to their high strength, toughness and wear resistance [1] . Medium-carbon steels have better hot workability and cutting properties, and are stronger and harder than low-carbon steels, and are widely used in industrial production such as machine tool spindles, engineering structural parts such as gears, and automobiles and ships [2] .Medium carbon steel billets are generally processed into bars, plates and sections by hot rolling and forging [3] . During the hot rolling process, especially in the hot rolling of bars, there is a phenomenon of "remagnetization" after demagnetization of the hot rolled bars, resulting in the so-called "remanent magnetization" phenomenon.…”

Residual magnetism is always of presence in the medium carbon steel formed in the hot rolling process even by the traditional demagnetization treatment. In order to eliminate the residual magnetism in the typical medium carbon steel, the steel was annealed at 650℃ for different holding time. It is found that, at the early stage of the annealing process, the residual magnetism in the steel decreases gradually with increasing the annealing time. When the annealing time reaches 60 min., The removed residual magnetism reaches a peak. It is attributed to the dissolution and the spheroidization of carbide structure during the annealing process, and the decrease of the micro-strain in the steel, as well. When the annealing time increased from 60 min. to 75 min., the residual magnetism increases with increasing the annealing time for the formation of the heterogeneous microstructure in the steel.

“…Beyond a threshold of 400 cycles, the corrosion rate of carbon-free bainite exceeded that of martensite, transforming the surfaceretained austenite in carbon-free bainitic steel to martensite. Conversely, the corrosion surface of carbon-free steel predominantly featured grooves, indicative of abrasive wear as the primary degradation process [16]. The recent surge in interest towards the incorporation of nanoparticles into steel microstructures aims to engineer new steel grades with enhanced mechanical properties.…”

The current study embarks on the exploration of the influence of varying heat treatments on the wear characteristics of medium carbon steel samples undergoing carburization. The investigation involved seven distinct cooling processes, utilizing a range of quenching media to cool the samples from elevated temperatures of 780℃ and 770℃. The carburized steel specimens were subjected to two tempering protocols at 230℃ and 250℃. A comparison was drawn against control samples that were neither heat-treated nor carbureted. The empirical findings suggest a significant reduction in key wear indices such as weight loss, cumulative volume lost, wear coefficients, and wear rates upon the repetition of heat treatment. The third heat treatment regimen demonstrated the poorest results in terms of the aforementioned wear indices, superseding the negative outcomes of the second heat treatment, which in turn exceeded the first. Distinctly, samples quenched with distilled water exhibited the most desirable characteristics, recording the minimal values for weight loss, cumulative volume lost, wear coefficients, and wear rates, when juxtaposed with other quenching media. Conversely, the highest values for these wear indices were observed in samples quenched with shampoo and, to some extent, motor oil.
