    The bond strength of Al + Al2O3 cermet coatings deposited by low-pressure cold spraying

    This article presents the bond strength of composite coatings built by cold spraying method. The composite A1-A12O3 coatings were made with the use of low pressure cold spraying (LPCS) equipment. The main aim of the study was to analyze the influence of thickness, roughness and waviness on the adhesive and cohesive properties of composite coatings. The experiments were performed at constant spraying parameters for different coating thicknesses within the range from 250 μm to 3000 μm. The use of manipulator allowed the uniform deposition of coatings. The coatings bond strength amounted up to 61 MPa. A significant effect of coating thickness on the nature of the failure was observed. Machining process influenced the coatings failure nature as well as bond strength value. What is more coating failure changed from adhesive into cohesive with increasing coating thickness.
