Adhesion Properties of Sprayed Coatings on Substrate Blasted by Multiangle Blasting

Adhesion properties on the substrate blasted by multi-angle blasting of white alumina girt are examined. The substrate of low carbon steel is blasted by two blasting angle in a blasting process. For example, the substrate was blasted by a low blasting angle, and blasted by a high blasting angle. The multi-angle blasting is shown as an effective blasting process to be obtain good adhesive properties though the experiments of zinc alloy sprayed coatings. The low blasting angle is contributed for contamination removal on the substrate surface. The high blasting angle is contributed for an effective surface roughness for better adhesive properties.
