“…In contrast, the friction behavior of the UNSM-treated specimen started fluctuating in the transition period from the running-in stage to the steady-state stage. This friction behavior usually occurs because of the initial surface roughness and the plastic deformation of contact interface by high contact stress [34]. In other words, the repeated sliding causes the contact area increase and results in the formation of a wear track on the surface.…”

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 techniques such as PVD and CVD have been applied to the cladding of the wear resistant layer on the die surface. Among the advanced techniques, powder plasma surfacing technology is one of the most promising process because its dense structure and better coating performance and especially for its wide range of material selection [8]. And the iron-based cladding alloys are extensively used in the industry for sliding wear application.…”

With the increasing demand for lightweight and lower fuel consumption and safety of automobile industry, lightweight materials of high strength steel (HSS) are more and more widely used. The hot stamping technology, which is determined by the inherent mechanical properties of high strength steel, makes molds prone to wear failure in the harsh service environments. In this paper, a finite element model is proposed for analyzing the value and distributions law of friction shear stress of contact surface of the pin disk. Through the simulation process of sliding wear, two kinds of different cladding materials of the pin specimens including H13 and Fe65, were experimented under three different loads by using the software ABAQUS. And then the pin-ondisk wear test at elevated temperature was conducted to verify the effectiveness of the simulation results. The results showed that the friction shear stress of pin with iron-based cladding and H13 steel was different under different loads, but the distribution was basically the same; the normal friction shear stress increased gradually along the direction of the pin movement, and the tangential shear stress increased gradually from the center of the pin to the outside of the circle; the value of the friction shear stress of the normal joints on the contact surface was periodically fluctuating in the whole dynamic analysis step, while it was basically stable in the tangential direction.

According to tribology theories and wear mechanisms, several techniques are used for preventing and reducing wear. In repair-maintenance welding which is one of these methods, surface of main material is covered with wear high resistant hardfacing materials and thus, materials can be used again in industry. The aim of this experimental study is determining of influences of farin (cement's raw material) and clinker (cement's semi finished product) on abrasive wear conditions of wear plates that were coated with hardfacing alloy and used as grinders in cement production. Coatings were deposited onto EU S355JO steel plates with shielded metal arc welding (SMAW) method by using five different commercial hardfacing electrode. Abrasive wear tests were done with dry sand-rubber wheel abrasive wear testing machine according to Procedure A indicated in ASTM G65 test standard. However in wear tests, farin and clinker abrasives were used instead of quartz abrasives which as stated in ASTM G65 standard. Thus, determination of abrasive wear resistances of wear plates were become more realistic. Microstructure examinations were done by using optical microscopy (OM) and scanning electron microscopy (SEM). Additionally, formed phases in hardfacing coatings were determined by X-ray diffraction (XRD) analysis for supporting microstructure examinations. Vickers hardness measurements of coatings were done in room temperature. 0.17341/gummfd.48584
