Researchers in Canada tested SiC-reinforced Al-12Si alloy coatings that were produced using the Cold Gas Dynamic Spraying deposition process. The composite coatings’ bond strengths and microstructures were evaluated, as well as the porosity and the SiC content. Bond strength evaluations were conducted using the ASTM Standard C 633-01. Master Bond EP15 was used to test a coating that was produced on grit blasted standard test samples. They were then machined flat and glued to an uncoated test sample. The bonding agent was also initially tested separately.1
