This study investigates the influence of substrate temperature on the adhesion strength of cold spray coatings. Copper, aluminum, and iron powders were deposited on preheated substrates similar in composition with the respective powder. Adhesion strength was determined by shear adhesion testing. The results show that substrate preheating improves adhesion strength for specific combinations of coating and substrate materials, likely due to the relief of thermal stress and the formation of an oxide layer on the substrate surface.
