Development of Corrosion Protection Coatings Based on Impact/Deposition Phenomenon of Supersonic Particles

Abstract

A coating process is necessary to satisfy various requirements for corrosion protection. Based on clarification of the impact and deposition phenomenon of supersonic particle, the control mechanism of temperature and velocity of the in-flight particle was devised. The coating method (Warm Spray) was realized for active materials such as titanium, metallic glass, titanium oxide and plastic, which are highly corrosion-resistant while they are difficult to be deposited in the air.
