Summary: The wear resistance of low carbon steel (LCS) was improved by embedding high chromium cast iron (HCCI) into LCS using the hot rolling technique. After hot rolling, the brittle HCCI layers were broken and dispersed randomly in the LCS matrix. The HCCI combined well with the LCS matrix without any unbonded region or voids, resulting in better wear performance for specimens with a larger area fraction of HCCI.

Summary: Research has found that skidding in rolling bearings can cause uneven vibration and surface wear, with tangential vibration containing both the rotational frequency of the roller and higher harmonics. Surface contact stress analysis shows that unstable shear stress variation induced by sliding in rolling contact is the root cause of tangential vibration. Further wear checks reveal that wear failure under sliding-rolling contact coincides with the shear effect of contact interfaces.

Summary: This study investigates the tribological properties of G350 grey cast iron in different microstructural conditions. Samples with different microstructures were produced through quench and temper heat treatments at various tempering temperatures. Pin-on-disc sliding wear tests were conducted to evaluate the performance. The results showed that increasing tempering temperature led to a decrease in hardness, and spheroidized carbide discs had higher volume losses compared to acicular martensitic discs. Subsurface deformation was observed in annealed pins and spheroidized discs.

Summary: In this study, a high chromium cast iron alloy was tested for dry-sliding linear wear under different loads. The influence of load on the microstructural behavior and wear mechanisms was investigated. It was found that plastic deformation of the matrix occurred at loads equal to or higher than the critical load. The dominant wear mechanism shifted from adhesive wear to abrasive wear with increasing load, leading to increased wear volume and rate.

Summary: The study investigated the sliding wear properties of G350 grey cast iron following different spheroidizing annealing durations. Most testing combinations resulted in mild wear, but severe wear was observed at the highest load and longest annealing times. Depth of subsurface deformation increased with annealing time, with load only affecting the depth by causing spallation of the affected surface layer at higher loads.

Summary: The tribological performance of Mn.P coating and PC/MoS2 coating were investigated and compared with AISI52100 steel, showing significant antifriction effects with less influence from slide-to-roll ratio changes for coated samples. As wear time increased, the running performance of Mn.P coating improved relative to PC/MoS2, but only one contact pair treated with Mn.P coating showed improved tribological behavior.

Summary: Few studies have been done on the wear resistance of nanoparticle-reinforced graphite ductile irons. This research investigates the effects of TiC-TiB2 nanoparticles on the microstructure and wear properties of graphite ductile irons. The addition of nanoparticles effectively refines the graphite nodules and substrate in the matrix, leading to reduced wear rate under different test conditions. The wear mechanisms observed are adhesive wear, abrasive wear, and oxidative wear. The improved wear properties are attributed to increased substrate hardness, separation of contacting areas, plowing inhibition, and resistance to plastic deformation.

Summary: This article proposes a Multi-Roll Solid-Liquid Cast-Rolling Bonding (MRSLCRB) process to fabricate Cu/steel cladding bars, using twin-roll casting technology and multi-roll groove rolling technology. The geometrical evolution of the cast-rolling area is studied to establish contact boundary equations and analyze mechanical schematics and metal flow. A 3-D thermal-fluid coupled simulation model is established to predict the Kissing Point (KP) height, average outlet temperature, and process window. The engineering cast-rolling force model is derived and verified, and the influence of process layouts and technological parameters on the cast-rolling force is analyzed. The temperature-pressure evolution and reasonable process window can be predicted, providing a significant basis for guiding equipment design and improving product quality.

Summary: A composite material consisting of high-chromium cast iron (HCCI) dispersed in low-carbon steel (LCS) was prepared through multilayer hot rolling to achieve good wear resistance and toughness. The microstructure and mechanical properties of the composite were investigated, revealing a well-combined interface with broken oxides and decarburization at the LCS side. The impact toughness of the composite material was significantly higher than that of the as-cast HCCI due to the addition of ductile LCS, but the wear resistance was slightly lower than that of HCCI.

Summary: Nitriding is a common process used in industry to enhance the tribological properties of components. This study investigated the influence of different ferrous layers formed by variant nitriding treatments on friction and wear performance, finding that a sulfide (FeS) layer produced the lowest friction and wear due to its lubrication properties. The research highlights how the type of ferrous layer can impact the tribological and tribochemical properties of nitride samples.

It found that the waste sand was more favorable for improving the overall friction and wear properties of the material compared to copper. Waste sand benefited the material by forming a friction layer, leading to increased friction coefficient and stability. Brake material with 10-15% waste sand showed excellent heat-fade resistance.

Summary: In this study, a elasto-plastic constitutive model of friction incorporating the concept of superloading surface was developed based on the subloading friction model. The proposed model achieves a smooth transition of friction by describing the evolution rule of structure, treating the state with static friction coefficient larger than kinetic friction coefficient as the bulkiness of structure. The positive definiteness of the plastic multiplier, loading condition, and material parameters were derived, and the validity of the proposed model in accordance with the subloading-friction model was confirmed through a stick-slip simulation of a mass-spring system.

Summary: This paper investigates the influence of preparation strategies on the lubrication properties of surface textures. Three laser scanning strategies are proposed to achieve a sinusoidal textured surface, and the evolution of surface structure and chemical composition is discussed. The findings show that ridge structures enhance anti-wear properties but also increase the friction coefficient. However, the oil cover preparation method prevents the formation of ridges and improves wettability.

Summary: This study presents a systematic approach to generating control signals for a tactile simulator that simulate the touch of textile fabrics. By using a friction modulation tactile surface and acquiring forces from real surfaces with artificial finger mimicking fingerprints, control signals are generated and processed in the frequency domain before sending them to the tactile stimulator. The study focuses on the potential benefits of incorporating fingerprint information in fabric simulations to achieve a more realistic tactile perception. A sensory analysis with 36 participants using the generated control signals showed better discrimination without fingerprint information.
