Summary: In this study, WC-Ni coatings were prepared using cold spraying and laser surface melting, forming a three-dimensional WC skeleton structure with uniform distribution. The remelted coatings with WC skeleton exhibited remarkable resistance against cavitation erosion by preventing crack propagation. The enhanced cavitation erosion resistance was attributed to the synergistic effect of the Ni binder phase and the hard WC phase.

Summary: This study assesses the synergic effect of cavitation erosion and corrosion on two HVOF-sprayed nickel-based cermet coatings, WC-NiCr and WC-H, on Monel K-500 substrate. It was found that WC-NiCr coating reduced the cavitation erosion losses in Monel alloy by 45% and had better corrosion results. SEM analysis revealed that the corrosive medium generated defects on the coating surface, increasing the cavitation erosion losses. WC-NiCr coating is recommended to enhance the cavitation-corrosion resistance in Monel K-500 alloy.

Summary: Directed energy deposition (DED) is a mainstream metal additive manufacturing technique that can fabricate near-net-shape components and repair damaged parts with a high build rate. This study utilized laser-assisted DED (L-DED) to print Monel K-500 parts from powder, optimizing key process parameters to achieve desired geometry and nearly full density. The resulting samples exhibited higher ultimate tensile strength and elongation to failure compared to their cast counterparts. The difference in grain structure, attributed to the process parameters, accounted for the anisotropy in mechanical properties. This work demonstrates the control of grain texture to achieve superior mechanical properties in metal parts printed by L-DED.

Summary: High-velocity oxygen-fuel spraying was used to deposit WC-10Ni (WN) and WC-10Co-4Cr (WCC) powders as coatings on a 1Cr18Ni9Ti stainless steel substrate. Despite having higher hardness and elastic modulus, the WN coating exhibited better resistance to corrosion in NaCl medium compared to the WCC coating. Both WN and WCC coatings showed an increase in volume loss rates as flow velocity in NaCl medium increased, and the corrosion mechanisms were compared and revealed.

Summary: This study investigates the effect of mechanical properties and microstructure on the sliding wear and cavitation erosion behaviors of cermet coatings deposited on AZ31 magnesium substrate via high velocity oxy-fuel (HVOF) spraying. The results show that the WC-Co-Cr cermet coating has superior resistance to cavitation erosion compared to WC-Cr3C2-Ni and WC-Co coatings. The erosion mechanism of the WC-Co-Cr coating exhibits uniform material removal, which slows down the erosion rate. The sliding wear behavior is strongly related to the mechanical properties of the coatings, with higher hardness and Young's modulus resulting in lower wear factors.

Summary: In this study, two cermet coatings were manufactured and their resistance to cavitation-silt erosion in simulated sea water slurries was investigated. The results showed that the Cr3C2-25(NiCr) coating had worse CSE resistance compared to the WC-10(Ni) coating, and its resistance was more affected by sand concentration and flow velocity. Both sand concentration and flow velocity had a positive effect on the CSE damage for both coatings, but sand concentration had a greater influence. The deterioration mechanisms of the coatings under different sand concentrations and flow velocities were also compared and revealed.

Summary: Fuel cells are efficient energy conversion devices with various applications. The proton conductivity of Polymer Electrolyte Membrane (PEM) is crucial for fuel cell performance. Developing alternatives to commercial PEMs based on costly perfluorinated ionomers is a pressing need. Sulfonated polyimides (SPIs) have shown better proton conductivity than commercial PEMs at lower hydration levels and higher temperatures, but finding alternative SPI PEMs requires extensive experimental efforts. Machine learning approaches can reduce these efforts and predict proton conductivity.

Summary: This paper presents an experimental study on the influence of air swirl vane angles on pollutants in a heavy oil fuel fired furnace. The results show that vane angles of 45 degrees and 30 degrees emit the least HC and CO, whereas a vane angle of 90 degrees emits the most. A vane angle of 45 degrees results in the lowest NOx emission. Furthermore, for complete combustion, the secondary air entry area should be twice the primary air entry area in the novel burner.

Summary: Small-scale, low-cycle fatigue experiments were conducted on hydrogen charged nickel specimens to identify potential intergranular crack initiation sites. A crystal plasticity model considering dislocation density and a hydrogen transport model based on slip-rate were developed to study the micromechanics. A fatigue indicator parameter (FIP) was introduced to model the crack initiation process by considering plastic slip, GB stress, and local hydrogen concentration. The analysis showed that special GBs retain more hydrogen due to low diffusivity, while random GBs quickly diffuse hydrogen to the bulk.

Summary: Thermal spray chromium carbide-based composites are extensively used in industry due to their superior oxidation resistance at high temperatures. This study compared the performance of HVOF sprayed coatings from an atomized chromium carbide-based feedstock with those from a conventional agglomerated and sintered feedstock. The coatings were exposed to high temperatures in air and steam environments to simulate industrial power plant working conditions. The results showed that the chromium carbide content remained stable in the atomized feedstock, while carbide dissolution was observed in the conventional feedstock. Air oxidation resulted in the formation of a coarse oxide surface, while steam treatment formed a finer and more uniform Cr2O3 surface. The Cr23C6-40NiCr coating exhibited an intact and crack-free oxide scale, and its microhardness was comparable to that of the Cr3C2-25NiCr coating.

Summary: The durability assessment of additively manufactured parts must consider both surface-breaking material discontinuities and porosity, and how these factors interact with as-built parts. The authors have previously shown how the Hartman-Schijve variant of the NASGRO crack growth equation can predict the durability of wire arc additively manufactured specimens with surface-breaking cracks due to surface roughness. This paper demonstrates that the same equation can also be used to predict the durability of specimens with failure caused by surface-breaking porosity.

Summary: This paper investigates crack growth in both additively manufactured (AM) and conventionally manufactured Inconel 718, as well as Inconel 625. It is found that when the crack growth rate (da/dN) is plotted as a function of the stress intensity factor range (& UDelta;K), there is considerable scatter. However, when da/dN is expressed in terms of the Schwalbe crack driving force (& UDelta;& kappa;), all curves collapse onto a single curve. This observation challenges the materials science community to address the underlying fundamental science.

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 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.
