I have been familiar with plasma spraying in one of the leading thermal spray research laboratories in North America; Centre for Advanced Coating Technologies at the University of Toronto since I started my PhD thesis under supervision of Professors Javad Mostaghimi and Thomas W. Coyle in 2001. Having access to various methods of thermal spraying, diagnostic tools, and processes simulation, I gained experiences in process, deposition, characterization, and simulation of various types of thermal spray coatings
