Study on the thermal conductivity measurement of steel-copper composite materials obtained by cold gas-dynamic spraying

In the article the influence of copper powder size distribution on structure and thermal properties of thick coatings is described. The coatings are obtained by cold spraying of composite materials with stainless steel‑based matrix. Also studied the possibility of metal‑matrix composite deposition, the average hardness of which is comparable to the sprayed coating of stainless steel without additives (250 HV and more) but with increased thermal conductivity

Keywords: cold spray, coating, thermal conductivity, composite materia.
