A process for coating a component and a coating system including a bond coat (46) on a superalloy substrate (44). A thermal barrier material (48) may be applied to the bond coat and a rare earth apatite (54) may be applied to the thermal barrier material (48) via one of Suspension Plasma Spray (SPS) and Solution Precursor Plasma Spray (SPPS) to form an exposed surface. The rare earth apatite (54) may be formed as Ca 2+y RE 8+x (SiO 4 ) 6 O 2+3x/2+y in which -2
