Summary: The adhesion strength of cold-spray coating is assessed through evaluating multiple flaws and property distributions. Two approaches, interfacial shear strength and fracture toughness, have been proposed for determining the adhesion strength. The interfacial shear strength approach combines fragmentation testing with a modified Weibull model, while the fracture toughness approach uses an electrical four-point probe to calculate the energy release rate.

Summary: The study found that in the cold spraying process, a softer aluminum substrate is more advantageous for adhesion than a copper substrate. Annealing can lead to thermal softening of the substrate, increasing the adhesion strength of the coating. The bonding between the cold-sprayed TiO2 particles and the substrate surface is mainly metallurgical in nature.

Summary: The influence of spray angles and particle velocities on cold spray deposition of IN718 powders was investigated. Particle velocity was found to have a greater impact on coating porosity compared to spray angle. The lowest porosity and surface roughness but highest compressive surface residual stress were achieved with a spray angle of 50 degrees and particle velocity of 920 m/s. Changing the spray angle had a greater influence on deposition efficiency.

Summary: This study investigates the modification of hydroxyapatite coating structure by changing the coating process and post-heat treatment. The novel Aerosol Cold Spraying system is used for the deposition of coatings, and Spark Plasma Sintering and Pressureless Sintering are employed for post-processing. The results show that homogenous buildup of hydroxyapatite is achieved using Aerosol Cold Spraying, but there are various pores and microcracks in the sprayed coatings. The thermal post-processing improves the adhesion bond strength and crystal size of the coatings.

Summary: The cold gas spray (CGS) technology enables the development of biofunctional coatings composed of 45S5 and PEEK, making it an interesting material for orthopedic applications. Different mixtures of 45S5 and PEEK powders were prepared and deposited on PEEK substrates by CGS. It was found that the deposition efficiency of the coatings is affected by the granulometry and 45S5/PEEK ratio, and the presence of glass particles improves the wear resistance of the coatings.

Summary: Tin oxide film with regular nano-channels was formed on the surface of cold sprayed tin coating by anodizing, and annealing the samples with water led to crystalline particles formation on the inner surface. The electrochemical performance of the nanoporous tin oxide film was evaluated, showing specific capacitance and enhancement of the active surface area. The investigation of orientation effect on capacitance revealed positive effects of (020) and (031) orientations but a sharp decrease in capacity for (110) and (011) orientations.

Summary: In situ-alloyed Ti6Al4V(ELI)-3at.%Cu was successfully manufactured by laser powder bed fusion. Stress relieving and annealing treatments resulted in microstructural changes, with an increase in β phase and CuTi2 intermetallic precipitates. The increase in Cu ions release from the β phase led to antibacterial behavior and inhibited biofilm formation.

Summary: Prealloyed Fe3Al with high density, good surface quality, and suitable mechanical properties was successfully manufactured using laser powder bed fusion. The presence of minor variations in aluminum content along the melt pool and the development of a weak texture along the building direction were observed in the microstructure. The mechanical properties were found to be temperature-dependent, with a significant loss in strength at higher temperatures due to plastic deformation and tribochemical wear.
