This study employs a hybrid experimental–statistical approach to identify the influence of key process parameters and their interactions, based on a systematic design of experiments. Five factors were investigated: total gas flow (TGF), fuel-to-oxygen ratio (F2O), powder feed rate (PFR), standoff distance (SOD), and coating velocity (CV). The effects of these factors on in-flight particle properties, process performance, and coating characteristics were analyzed. Nondestructive evaluations, including deposition efficiency, surface roughness, and surface hardness, were directly compared with microstructural measurements. In contrast to previous studies, TGF emerged as the most influential parameter, exerting a stronger effect on particle properties, process performance, and coating characteristics than F2O. Significant interactions were identified, including the combined effects of TGF and F2O on roughness and hardness, TGF and PFR on deposition efficiency, and TGF and SOD on surface roughness. This investigation advances beyond validating known correlations by uncovering nuanced multidimensional interactions, offering a robust framework for optimizing WC-CoCr coatings.

In this work, atmospheric plasma spraying technology was employed to prepare novel high-entropy rare-earth tantalate (Nd0.2Dy0.2Ho0.2Y0.2Er0.2)TaO4 (HE-RETaO4) coatings on the surface of nickel-based alloys. The as-sprayed HE-RETaO4 powders undergo a ferroelastic phase transition from the monoclinic (m) phase to the metastable tetragonal (t′) phase during the spraying process. Owing to the influence the cationic radii of multispecies HE-RETaO4, its phase transition temperature is lower than that of YTaO4, leading to the formation of a ferroelastic domain toughened structure at lower temperatures. Under the plasma flame assessment at 1200 and 1300 °C, the insulation temperatures of the HE-RETaO4 coatings are 220 and 200 °C, respectively. The sluggish diffusion of HE-RETaO4 hinders diffusion of elements, ultimately engendering a profusion of equiaxed grains with comparable aspect ratios and a substantial divergence in energy between intragranular regions and boundaries. In addition, the microcracks generated within the HE-RETaO4 coatings rapidly expand along the high-energy grain boundaries of the equiaxed grains, eventually leading to mechanical delamination and coating failure.

Large-size 410 stainless steel (410SS) MF particles are mixed into Al powder during spraying to promote the plastic deformation of Al layer and form dense coatings. The effects of cold spray process parameters on the quality of Al coatings were investigated, and the optimal process parameters are obtained. The experimental results show that the porosity of Al coatings decreases with the increase of MF particle content. When the MF ratio is greater than 40 vol.%, the microstructure of Al coatings is dense and the porosity is lower than 0.1%. As the content of MF particles further increases, the micro-hardness of the Al coatings slightly increases to 51.91 HV0.1, and the bonding strength increases to 126.3 MPa. The sealing performance test shows that the optimal spraying angle is 15°, where the coated specimen can withstand a maximum pressure of 1 MPa for over 10 minutes.

Despite these advantages, challenges like porosity and residual stresses introduced during deposition necessitate post-deposition treatments to enhance mechanical properties. This study explores the evolution of microstructure and residual stress and their influence on hardness and tensile properties in cold-sprayed Scalmalloy deposits produced using helium (He) and nitrogen (N2) as carrier gases, followed by direct aging and solution treatment with aging. He-sprayed deposits exhibited lower initial porosity (0.12 ± 0.03%) than N2-deposits (1.20 ± 0.51%). Solution treatment increased porosity to 6.9% (He) and 2.5% (N2) due to gas expansion within defects, while porosity remained unchanged after direct aging. Direct aging significantly reduced residual stresses, with a 69% reduction in He-deposit and a 55% reduction in N2-deposit. The formation of Al3(Scx, Zr1−x) precipitates during aging led to precipitation strengthening, increasing hardness by 20% (He) and 25% (N2) relative to the as-deposited condition. Hardness increase contributed to a 23% rise in tensile strength in He-deposits (575 ± 9 MPa) and 58% in N2-deposits (542 ± 23 MPa). Additionally, profilometry-based indentation plastometry revealed anisotropy in pileup distribution, which was more pronounced in the as-deposited state but significantly reduced after aging, indicating improved structural uniformity.
