Summary: In this study, low-power compact plasma spray (CPS) equipment was used to deposit Cr3C2-based cermet coatings on carbon steel substrate. Design of experiment and ANOVA analysis were employed to select and optimize the spraying parameters and evaluate the effect of these variables on the morphology and mechanical properties of the coatings. By optimizing the processing parameters, dense and compact coatings with high hardness and good adhesion strength were obtained.

Summary: It is important to understand the behavior of Cr3C2-NiCr hardmetal coatings under different conditions. This study investigated the effects of oxidation, hot corrosion, and wear on these coatings on stainless steel substrates at different temperatures and time periods. The properties of the coated samples were examined using various techniques, and it was found that oxidation and hot corrosion led to changes in the microstructure and protective features of the coatings, while wear resulted in volume losses due to friction forces.

Summary: This study investigated the erosion resistance of two coatings at 25 degrees C and 900 degrees C, and found that the C1 coating had better erosion resistance than the C2 coating at both testing temperatures and the three impact angles. The C2 coating was 11% harder than C1 but had a 62.2% decrement in its K-IC value. This was due to the presence of SiC hard particles inducing minor cracks and the larger propagation of cracks in the C2 coating.

Summary: The microstructural studies of 75 wt% Cr3C2- 25 wt% NiCr-based composite clads developed through laser and microwave energy on a T91 steel substrate were compared. Both processes exhibited better metallurgical bonding with the substrate. The laser-clad showed a dense solidified structure with a rich Ni phase, while the microwave-clad had hard chromium carbide particles dispersed within the nickel matrix. Despite the presence of chromium carbides, iron nickel, and chromium-nickel phases, microwave-clads also contained iron carbides. The laser-clad had a higher microhardness (1142 & PLUSMN; 65HV) compared to the microwave-clad (940 & PLUSMN; 42 HV). The laser-clad exhibited superior wear resistance, while the microwave-clad experienced more surface damage and material loss.

Summary: This study used a novel ethanol-fueled HVOF process to prepare Cr3C2-25wt%NiCr hard-metal coatings on stainless steel substrates. The influence of different stoichiometry conditions on the microstructure and performances of the coatings was investigated. The results showed that the stoichiometry factor has little effect on the phase composition but has a significant impact on the microstructure and properties of the coatings. When the stoichiometry factor is <1, a denser and higher erosion-resistant Cr3C2-NiCr coating is obtained, which differs from the results obtained using kerosene-fueled HVOF processes.

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.
