Summary: The study aimed to investigate the microstructural development and wear performance of Nb and Mo added hypereutectic WCI hardface deposits, with W and V as minor additives. It was found that the addition of Nb and Mo resulted in the formation of MC carbides, leading to grain refinement and higher wear resistance. XRD analysis showed the existence of MC carbides in alloys with Nb and Mo additions, contributing to improved wear resistance.

Summary: Abrasive processes, specifically local slip, play a significant role in the friction and wear of vehicle tires. Understanding the dynamic contact between rubber blocks and abrasive surfaces is crucial for analyzing tire tread friction and wear mechanisms. Detailed consideration of realistic transient dynamics is essential for accurate characterization beyond typical abrasion testers.

Summary: Al-10.0 vol% (TiC and GNPs) composites were fabricated by powder metallurgy with different volume ratios of TiC and GNPs. The results showed that as the TiC-to-GNPs ratio decreased, the particle free zones (PFZs) in the composites decreased and the distributions of reinforcements became more uniform, resulting in increased hardness and wear resistance. The composite with Al-8.5 vol% TiC-1.5 vol% GNPs exhibited the highest hardness and the best wear resistance. However, the hardness and wear resistance of the composite dropped drastically when the GNPs fraction increased due to GNPs agglomeration.

Summary: This study investigated the wear resistance of Fe-Cr-C-B hardfacing alloy modified with nano-CeO2 and found that nano-CeO2 promoted the heterogeneous nucleation of primary carbide, improving wear resistance and bending strength. Excessive nano-CeO2 did not have a significant effect on the refinement of primary carbide, although it did contribute to bending strength improvement without enhancing wear resistance.

Summary: The addition of Ce element can significantly improve the microstructure of ZK60 alloy, reducing grain size and increasing the total fraction of precipitates, thereby enhancing the mechanical properties of the alloy. Ce element can also improve the wear resistance of the alloy, enhancing wear resistance under low load conditions and providing a protective oxide layer under high load conditions. However, under severe oxidation conditions, the microstructural evolutions caused by Ce addition do not contribute to the enhancement of wear resistance.

Summary: This research explores the effects of preheating, gas-shielding, and buffering conditions on the microstructure and wear resistance of Fe-Cr-C hardfacing alloy in flux-cored arc welding (FCAW). The results show that these conditions can improve the quality, dilution, and weldability of the hardfacing weld. Buffering can combine the hardfacing and structural steel base, reducing crack and carbide precipitation. The combination of buffer and hardfacing layers affects crystallite size and fraction ratio, increasing elemental diffusions.

Summary: This study investigates the tribological behavior of Indian rail track and wheel materials under different contaminants. The experimental analysis is conducted using a pin-on-disc tribometer in ambient conditions. Results show that sand increases friction force and wear depth, while oil reduces friction and wear. Mist and leaves also decrease friction and wear, with leaves having a higher effect than mist. The study also examines the effect of load on various contaminants, finding that increased load leads to increased friction force and wear for all contaminants.

Summary: The objective of this study was to investigate the effect of vanadium on wear and corrosion resistance in Fe-Cr-C hardfacing alloy. The addition of vanadium resulted in the formation of carbides and reduction in size and volume fraction of primary carbides. However, the vanadium-free coating exhibited maximum hardness and wear resistance while having the highest corrosion rate. The optimal vanadium content was found to be 2% by weight.

Summary: In this study, Ti-xFe (x = 3,5,9 wt%) alloys were surface modified by micro-arc oxidation (MAO) to improve their antimicrobial properties and biocompatibility. The results showed that increasing the oxidation voltage greatly enhanced the roughness and hydrophilicity of Ti-xFe-MAO alloys. The Ti-xFe alloys micro-arc oxidized at 250 V and 300 V exhibited improved corrosion resistance and excellent antimicrobial and cytocompatibility properties, making them suitable for orthopedic implant materials.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
