An experimental evaluation of the thermal interface resistance between cold sprayed copper/ laser-textured alumina bi-layered composites

•Cu - Al2O3 bi-layered composites are manufactured using cold spray copper deposition.•Al2O3 substrates are laser-textured to create different ordered surface topographies.•Thermal interface resistance (TIR) at the Cu - Al2O3 interface is measured using light-flash analysis.•The lowest measured range was 1.5610−6−1.4910−9m2K/W, for a temperature range of 20–500 ∘C, and a corresponding adhesion strength of 16.79 MPa.•The results suggest some correlation between Al2O3 substrate surface topography and the TIR, and an inverse relationship with adhesion strength.
