| Abstract: | Characteristics and process principle of cold gas spray process were introduced briefly and deposition process of supersonic Cu particles impacting onto substrate was analyzed. Bonding mechanism of coatings was analyzed by SEM. It was found that particle bonding between coating and substrate or among particles mainly belonged to mechanical bite and bonding among coating partially belonged to metallurgy and physical bonding. |
| Keywords: | cold gas spray deposition process bonding mechanism |
