Abstract: A coating system and a method of forming the coating system capable of enabling components to survive in high temperatures environments, such as the hostile thermal environment of a gas turbine. The coating system is formed of a ceramic powder having powder particles each having an inner core formed of a first material and an outer region formed of a second material on the surface of the inner core. The inner core has a lower thermal conductivity than the outer region and the outer region has improved erosion resistance relative to the inner core.
