Experimental and computational studies were conducted to analyze the cold spray coating as it is
sprayed at varying angles relative to the substrate surface. The prepared coatings were compared
in terms of adhesive bond strengths. The results show that the coatings sprayed at angles gave up
to 25% higher adhesive bond strengths. Computational analysis using Abaqus software was
performed to validate this observation.
