Microstructure and Microhardness of Cold‐Sprayed CuNiIn Coating

Microstructural investigations on bonding mechanisms of cold-sprayed copper with SS316L steel

“…Bonding at the interface governs by the severe plastic deformation (High-strain deformation) of the materials, and due to adiabatic shear instability (ASI) at the interfaces, which leads to the metal-jetformation [27]. The high-velocity particle striking causes in oxide layer break down from the surfaces, providing a true particle-to-substrate contact [6,7,15,[28][29][30][31][32][33]. This true contact of the particles with the substrate may lead to jetting formation governed by ASI [10][11][12]16,23,34,35,[35][36][37][38][39][40][41][42][43].…”

Single-Step Production of Nanostructured Copper-Nickel (CuNi) and Copper-Nickel-Indium (CuNiIn) Alloy Particles

“…[21][22][23][24][25] Several methods have been studied to prepare nanostructured CuNi and CuNiIn alloy particles including polyol synthesis, [6] wetness impregnation, [8] micro-emulsion method, [9] mechanical milling, [17] arc plasma evaporation, [26] electro deposition, [27][28][29][30] atomization, [31] reduction of metal oxides by mechanical and chemical routes, [32] mild hydrothermal synthesis, [33] hydrothermal reduction, [34] solution combustion synthesis, [7,35,36] and cold spray. [37] Among them, spray pyrolysis is a versatile technique to produce nanostructured metallic and alloy particles in one step. The particle composition and chemical content can be easily controlled in the spray pyrolysis process.…”
