Event Description:

Speaker: Sanjay Sampath, Professor of Materials Science and Engineering, an affiliate Professor of Mechanical Engineering and Director of the Center for Thermal Spray Research at Stony Brook University

Topic: Protecting Engineering Components with Thermal Plasma Spray Painting

Many engineering components from automobiles to aero engines to heavy machinery experience harsh environmental exposure such as high temperature, wear and corrosion. Metallic materials that perform the structural functions require protective coatings to enable their operations in these situations. These coatings are usually made of ceramic or metallic materials and need to be deposited onto the metallic structures. Since the coating materials have very high melting points, heat sources required to melt and spray these materials are needed. Thermal plasmas formed through dissociation and ionization of inert gases provide very high temperature sources with temperatures exceeding 15000 K and as such allow melting and projecting of particles. So-called
plasma spray technology is widely used in engineering industry. This presentation will discuss the technology and provide examples of day-to-day applications which allow aircrafts to fly more efficiently, power plants to reduce their carbon dioxide emissions, and even allow orthopedic implants to improve functionalities.
