“…The carbon rich layer at the subsurface will transform to other microstructure (such as martensite and bainite) depending on the rate of cooling used after the carburization process. Zhang et al [1] used alcohol and kerosene as carburizer to produce 2.5 mm thick of bainite and martensite on the subsurface of steel specimens. The bainitic steel is produced by immerging the carburized specimens into a salt bath at 230 o C for 48 hours before being air cooled to room temperature.…”

Abstract. Experiments have been carried out to investigate the effect of carburization process on the sliding wear resistance of mild steel. The carburization process was conducted in carbonate salts mixtures of Na2CO3-NaCl. Carburization followed by water quenching resulted in the formation of martensite with a hardness of 900 HV in the subsurface, up to the depth of 400 µm. This hardness value was substantially higher than the non-carburized steel which had a hardness of 520 HV. In the initial stage of sliding in air, abrasive wear and cluster of fine cavities due to adhesion were formed. This was followed by the formation of large-scale fracture at the cavities. The high hardness of the carburized steel reduced the severity of adhesive wear and thus the tendency of the worn surface to fracture.

“…They concluded that the formation of this fine microstructure resulted in slight increase in wear resistance. In another study, nanostructured carbide-free bainite was produced in a case-carburised layer, and it was demonstrated that the structure outperformed somewhat harder martensite [6]. The differences in behaviour were small under low applied loads (where mild wear dominated with debris being predominantly in the form of oxide).…”

The abrasive wear of three metallurgical structures with radically different hardnesses have been investigated for the same steel. The particular steel concerned is a recent innovation capable of generating extremely fine distributions of crystals. The austenite in the alloy nevertheless has the capability of uniformly transforming into extremely fine pearlite, nanostructured bainite, and plate martensite. It is found that although the abrasion rates and wear coefficients are not very different for the three states, the mechanisms of abrasion are quite different. We report detailed characterisation experiments together with comparisons with commercially available steels subjected to identical tests.

“…Next-generation structural steels such as ultrahigh-strength transformation-induced plasticity (TRIP)-aided steels with a martensite/bainitic ferrite matrix-i.e., TRIP-aided martensitic (TM) steel [9][10][11], quenching and partitioning steel [12,13], and nanostructured bainitic steel [14,15]-are being considered for use in fabricating precision gears owing to their high toughness and fatigue strength [10][11][12][13][14][15][16]. Sugimoto et al [17,18] reported that fine particle peening increases the rotational bending and torsional fatigue strength of heat-treated TM steel by imparting a significantly high hardness and compressive residual stress onto the surface-hardened layer.…”

Abstract:The torsional fatigue strength of newly developed case hardening steel, i.e., transformation-induced plasticity-aided martensitic steel subjected to vacuum carburizing followed by fine particle peening, was investigated for the fabrication of downsized precision gears with high torque capacity and wear resistance. The surface-hardened layer properties-i.e., high Vickers hardness, high compressive residual stress, and a large amount of retained austenite-considerably increased the torsional fatigue limits of vacuum-carburized and fine particle peened TM and JIS-SNCM420 steels, although the notch-sensitivity to fatigue was increased. The relation between torsional and rotational bending fatigue limits for the smooth specimens was found to be between the maximum principal stress and the minimum shear strain energy criterions. On the other hand, this relation for the notched specimens was represented through the maximum principal stress criterion.
