Summary: FeNiCrAl-B4C and FeNiCrAl-B4C-TiB2 coatings were successfully deposited on Q235 steel substrates using high velocity arc spraying technology. The wear resistance of FeNiCrAl-B4C-TiB2 coating was significantly higher than that of FeNiCrAl-B4C coating, mainly due to the addition of TiB2 reinforcement and the formation of hard phases.

Summary: In this study, a dense Fe-based metallic glass coating was obtained by laser cladding on stainless steel substrates. The results showed that high thermal energy and dilution can provide coatings with high hardness and wear resistance, although complete amorphous coatings were not achieved. Laser cladding can be an alternative to the conventional thermal sprayed process for the production of coatings requiring high hardness and wear resistance.

Summary: TiAl intermetallic compounds are a new type of high-performance lightweight structural material that is widely used in various fields. The addition of titanium carbide (TiC) as a reinforcing phase can enhance the mechanical properties, wear resistance, and heat-resistance stability of TiAl intermetallic compounds. The research revealed that the particle size of the mixture powders decreased with longer ball milling time, and Ti(Al) solid solution appeared as the milling time increased to 30 hours. The coatings sprayed at 550 degrees C exhibited the lowest average porosity and the same phase compositions as the mixture powders.

Summary: Increasing the Al content in the Fe-14%Mn-1.05%C steel led to larger austenite grain size, reduced carbide precipitation, higher yield strength, hardness, and wear resistance but lower tensile strength, ductility, and energy absorption capability. Wear mechanism was identified as abrasive wear in the form of parallel grooves on the worn surfaces. Additionally, increasing Al content decreased friction coefficient, weight loss, and surface damage.

Summary: Ti(CN)?Fe composites were hardened by refining microstructure and strengthening metallic phase through low-temperature/short-time sintering of nanocrystalline composite powders. The enhanced hardness of the composites resulted from uniform microstructure with reduced grain size, short Fe binder mean free path, and solid-solution strengthening of the Fe binder by the Ti solute. The Ti(CN)?Fe composites hardened in this way could expand the application range of Ti(CN)-based composites in mechanical parts.

Summary: The combined effect of cooling rate and microalloying on Cu-Zr alloy has been studied. A higher cooling rate promotes the formation of B2 CuZr austenite, while the addition of 0.5 at. % Fe promotes the formation of B19' martensite, resulting in improved wear resistance for 2 mm samples. For 4 mm samples, a lower cooling rate leads to the formation of multiphase intermetallic, and microalloying with 0.5 at. % Fe results in a relatively large volume fraction of B33 CuZr martensite, leading to reduced wear resistance.

Summary: In order to improve the toughness of Fe-B alloys, a method to break the continuous network of eutectic Fe2B by adding K2SO4 and heat treatment was attempted. The addition of K2SO4 resulted in the formation of a new phase α-MnS and increased the circularity value of M2B particles. The impact toughness of the alloy increased significantly, while the hardness remained unchanged. The wear behaviors of the alloy were also investigated and discussed.

Summary: Mo-based amorphous coatings exhibit better wear resistance than Fe-based amorphous coatings, despite having slightly lower hardness. At elevated temperatures, weak bonding of the inter-splat interface and the formation of hard α-Fe2O3 debris deteriorate the tribological responses of the coatings.

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.
