recommendations! Published in 2019 at "Advanced Engineering Materials"

DOI: 10.1002/adem.201900988

Abstract: Columnar‐structured thermal barrier coatings (TBCs) manufactured by electron beam‐physical vapor deposition (EB‐PVD) are well known to exhibit high strain tolerance. However, as EB‐PVD is a high‐vacuum process, it is expensive. Suspension plasma spraying (SPS) and… read more here.
