Summary: The application of fused tungsten carbides in nickel-based alloys is crucial for improving tooling equipment wear resistance in the mining industry. However, FTCs are thermally unstable and may dilute under excessive energy input during welding. Factors affecting dilution are diverse and not fully understood, with existing literature focusing on melt bead characteristics during gas metal arc welding. The study found that the droplet transfer mode has a significant impact on the degradation kinetics of FTCs, with globular transfer mode leading to greater degradation compared to short-arc mode due to higher process power and droplet temperature.

Summary: This research investigates the wear characteristics and wear resistance of composite powder coatings containing different chromium concentrations, deposited by supersonic flame jet. It was found that with increasing chromium concentrations, wear intensity decreases and reaches minimal values at 16% Cr. Coatings with 20% Cr exhibit increased wear intensity due to the absence of B and Si components, resulting in a lack of inter-metallic structures with high hardness and wear resistance.

Summary: This study enhances the wear resistance of medium carbon Cr-Ni austenite stainless steel by using shielded metal arc welding. The precipitation of carbides formed by Cr, Mo, and V in the austenite matrix and at the grain boundaries contributes to the high surface hardness (HB 300-500) of the deposited hardfacing metals, resulting in improved wear resistance.

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: Tristelle 5183 (Fe-21%Cr-10%Ni-7%Nb-5%Si-2%C in wt%) is an alternative to cobalt-based alloys for wear resistant hardfacing applications. The gas atomised powder was consolidated using hot isostatic pressing (HIPing) at 1120 +/- 10 degrees C, resulting in a microstructure containing fcc gamma-Fe, NbC, and M7C3. After HIPing, a wide distribution of gamma-Fe grain sizes were found, with larger grains exhibiting sub-grain structures and smaller grains containing annealing twins. This study demonstrates the potential for HIPing hardfacing alloys to achieve a fine scale homogeneous microstructure.

Summary: In this study, the cold spray technique was utilized to deposit nickel and titanium coated diamond powder on cast iron and aluminum substrates. The deposition mechanism was analyzed by observing the diamond powders before and after the process using a microscope and scanning electron microscope (SEM). The study also investigated the adhesion response of the Ni and Ti coatings. Pin-on-disk tests were performed to identify the abrasion mechanism of the coated samples and evaluate the wear resistance of the Si3N4 ceramic balls. Experimental tests were conducted to determine the significant operating variables.

Summary: By modifying the CO2/CO ratio in different atmospheric gas conditions, the sintering of FeCrCB alloy powders can be improved to enhance the hardness and abrasion resistance of hardfacing coatings. Under a 10C atmosphere, a higher microhardness and abrasion resistance were observed due to the formation of more hard phases, while the presence of CO led to lower abrasion resistance through the formation of higher volumetric fractions of eutectic phases.

Summary: In this study, homogeneous and functionally graded TiN thin films were produced using the grid-assisted magnetron sputtering technique. The wear resistance of the TiN films was evaluated using ball-cratering micro-abrasive wear test and nanoscratching test. The results showed a 33.3% increase in wear resistance for the functionally graded TiN thin film compared to the homogeneous TiN thin film. This increase was attributed to the higher resistance to crack nucleation and propagation and better adhesion to the substrate demonstrated by the functionally graded TiN thin film in the nanoscratching tests.

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.
