Aerosol deposition of ceramic coatings for high performance machine insulation 

This project will demonstrate the feasibility of using aerosol deposition to manufacture ceramic insulated wire (both bare nickel-coated copper and as a top-coat of ceramic on polymer). Such ceramic insulated wire could either a) significantly increase the operating temperature of machine insulation or b) significantly increase the partial discharge endurance. The project will scale previous tests carried out on flat insulation samples that showed a ceramic layer could be deposited without harming the underlying insulation while delivering a 70x increase in lifetime under partial discharge. The work will examine the feasibility of placing these coatings onto round wire / hairpin samples.
