| Outline of Final Research Achievements |
For purpose of aerospace application of light materials, the functional metal coatings such as Cu, Ni and Ti were formed on plastic substrate by using the gas tunnel type plasma spraying. Metal coatings with 50-100 micrometer in thickness were successfully deposited on the PET surface by this gas tunnel type plasma spraying under selective operating conditions using a small power of 10 kW or less. The microstructure and mechanical properties of these high functional coatings were clarified under various condition. Also, a small power of 3kW gas tunnel type plasma spraying apparatus was developed by improving the plasma torch design, and it was applied to plasma spraying of Cu metal materials. As the results, good quality Cu coatings were obtained on the plastic substrate, with almost no oxidation of Cu under the small power operating condition.
