LAMP is used to improve upon the process of Thermal Barrier Coating (TBC) deposition and enhance the material properties of TBC. LAMP is proposed to give better bond strength as a metallurgical bond is formed between the coating and the substrate.
Improved life and operating temperatures of the coatings can result in increased efficiency of operation of the turbines and engines and results in better cost efficiency. Functional grading of the 8% Yttria stabilized Zirconia and NiCoCrAlY TBC is evaluated for thermo mechanical properties such as residual stress accumulation, surface roughness, microhardness and microstructure. The LAMP is optimized by using Taguchi method of Design of Experiments to obtain the improved TBC.
