“…All the Zn coatings show higher FWHM than the Zn powder, and Zn coatings after heat treatment show lower FWHM than the as-sprayed Zn coating. FWHM is typically relative to the grain refinement, residual stress, and plastic deformation within the cold-sprayed metal coatings [ 16 , 26 ]. Peak broadening, as well as the increase in FWHM, can be attributed to an accumulation of stacking faults and structural disorders, grain refinement as well as increased stress [ 12 ].…”

“…Cold-sprayed metal coatings are formed by plastic deformations of metal particles due to the high-velocity impact. The inter-particle bonding interface and the coating/substrate interface are weak and mechanically interlocked, which results in overall poor ductility with brittle fractures commonly occurring [ 16 , 17 ]. To attain higher bonding strength and promote the overall coating performance, post-process heat treatment is usually conducted on the cold-sprayed coating.…”

The influence of post-process heat treatment on cold-sprayed Zn coatings on the Mg alloy substrate was investigated at different temperatures (150, 250, and 350 °C) and times (2, 8, and 16 h). Phase, microstructure, microhardness, and tensile strength of Zn coatings were analyzed before and after heat treatment. Corrosion properties of Zn coatings after heat treatment were investigated in simulated body fluid by using potentiodynamic polarization and immersion testing. Results show that although the heat treatment presented little effect on phase compositions of Zn coatings, the full width at half maxima of the Zn phase decreased with the heat temperature and time. Zn coatings presented comparable microstructures before and after heat treatment in addition to the inter-diffusion layers, and the inter-diffusion layer was dependent on the heat temperature and time. Both the thickness and the microhardness of inter-diffusion layers were increased with the heat temperature and time, with the largest thickness of 704.1 ± 32.4 μm and the largest microhardness of 323.7 ± 104.1 HV0.025 at 350 °C for 2 h. The microhardness of Zn coating was significantly decreased from 70.8 ± 5.6 HV0.025 to 43.9 ± 12.5 HV0.025, with the heat temperature from the ambient temperature to 350 °C, and was slightly decreased with the heat time at 250 °C. Although the tensile strength of Zn coating was slightly increased by heat treatment, with the highest value of 40.9 ± 3.9 MPa at 150 °C for 2 h, excessive heat temperature and time were detrimental to the tensile strength, with the lowest value of 6.6 ± 1.6 MPa at 350 °C for 2 h. The heat temperature and heat time presented limited effects on the corrosion current and corrosion ratio of the Zn coatings, and Zn coatings before and after heat treatment effectively hindered the simulated body fluid from penetrating into the substrate. The corrosion behavior of Zn coatings was discussed in terms of corrosion products and microstructures after immersion.

“…An in-depth review of the advancements in manufacturing and processing can be found in this recent article [ 56 ]. One of the additively manufacturing techniques, to obtain Fe surface with desired defects and grain refinement for degradation, is called cold gas dynamic spraying [ 58 ]. It is a high-pressure powder processing technique, utilizing compressed gas to propel metal powder at a large temperature range.…”
