An atmospheric plasma spray and electron beam-physical vapour deposition for thermal barrier coatings: a review

Thermal Barrier Coatings (TBCs) have been the topic of scientific research and development in surface engineering. TBCs provide effective surface protection onto the hot components of gas turbines and aero engines, enabling them to operate at high inlet gas temperatures. This paper aims to present state-of-the-art research contributions to strengthen the understanding of growth and development in the ever-increasing field of TBCs. The paper emphasises and consolidates major research progress and contributions carried out in the literature and briefly surveyed in the two most promising research categories, viz. growth and development in deposition techniques for TBC and exploration of TBC materials. A review will help the research community to understand the existing deposition processes and their contribution to future needs.
