| Abstract: |
Plastics are widely used due to the high corrosion resistance, small specific density and high deformability. The fabrication technology of thin coatings is not established because of difficulty in avoiding presence of pin-hole in the coatings obtained. In addition, a repair method is required to damage areas of the plastic lining stuffs. Although coating of plastics by a thermal spray technique was reported, it seemed to differ from the original plastics as feedstock in terms of some properties. For example, the coatings tended to have brittle nature. Development of Warm Spray apparatus, however, enabled plastics such as polyethylene to be coated on the metal substrate. The polyethylene coatings obtained indicated no thermal deterioration during the fabrication process. In addition, the impermeability of the coatings was attained at a thickness of 50 ìm.
