“…This superior wear resistance of the bainitic steel could be attributed to (i) the high strength and toughness of the bainitic microstructure, (ii) the effectiveness of the carbon enriched film-like austenite formed between the ferrite in preventing crack propagation and (iii) the formation of extremely fine and hard ferrite-phase microstructure at the surface of the bainitic microstructure during sliding. Izciler and Tabur [2] and Ulutan et al [3] reported that the formation of martensitic microstructure in the carburization process resulted in an increase in the abrasive wear resistance of steel. Bensely et al [4] found that deep cryogenic treatment applied to the carburized steel after quenching resulted in higher conversion of austenite to martensite and induced precipitation of finer carbides, and thus an increased hardness and wear resistance.…”

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.

“…In addition, it is well known that several types of wear mechanisms take place for metallic materials during wear processing simultaneously, where a great amount of carbon and oxygen can be formed during wear processing in steels. In general, a carbon-rich tribo-layer can be formed at the contact interface during sliding [39]. …”

Abstract:A comparative study of the microstructure, hardness, and tribological properties of two different AISI H13 tool steels-classified as the bulk with no heat treatment steel or the 3D-printed steel-was undertaken. Both samples were subjected to ultrasonic nanocrystalline surface modification (UNSM) to further enhance their mechanical properties and improve their tribological behavior. The objective of this study was to compare the mechanical properties and tribological behavior of these tool steels since steel can exhibit a wide variety of mechanical properties depending on different manufacturing processes. The surface hardness of the samples was measured using a micro-Vickers hardness tester. The hardness of the 3D-printed AISI H13 tool steel was found to be much higher than that of the bulk one. The surface morphology of the samples was characterized by electron backscattered diffraction (EBSD) in order to analyze the grain size and number of fractions with respect to the misorientation angle. The results revealed that the grain size of the 3D-printed AISI H13 tool steel was less than 0.5 µm, whereas that of the bulk tool steel was greater than 4 µm. The number of fractions of the bulk tool steel was about 0.5 µm at a low misorientation angle, and it decreased gradually with increasing misorientation angle. The low-angle grain boundary (LAGB) and high-angle grain boundary (HAGB) of the bulk sample were about 21% and 79%, respectively, and those of the 3D-printed sample were about 8% and 92%, respectively. Moreover, the friction and wear behavior of the UNSM-treated AISI H13 tool steel specimen was better than those of the untreated one. This study demonstrated the capability of 3D-printed AISI H13 tool steel to exhibit excellent mechanical and tribological properties for industrial applications.

“…Various factors such as heat treatment [8], environmental temperature [9], residual stress [10] and chemical element [11] were taken into consideration towards improving fatigue performance of the material. Surface treatment [12] and wear resistance [13] were another two focusing issues. Surface nitriding treatment and laser surface hardening were still the main directions to improve the wear resistance of tool steel.…”

Effects of tempering temperature on the microstructures and low temperature impact toughness of 42CrMo4-V steel were investigated. Microstructures of 42CrMo4-V steel after tempering at 570-720 • C for 3 h were experimentally investigated using scanning electron microscopy (SEM), electron back-scattered diffraction (EBSD), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The results showed that the carbide precipitation sequence of 42CrMo4-V steel is M 8 C 7 → M 3 C and the absorbed energies of 42CrMo4-V steel increase greatly from 21.7 J to 132.3 J with increasing tempering temperature from 570 • C to 720 • C. The changes of impact toughness with increasing tempering temperature were attributed to the softening of matrix, the evolution of carbide precipitates and grain structures.
