Electrolytic codeposition is a promising alternative process for fabricating MCrAlY coatings (where M = Ni, Co, or Ni + Co) for protecting high-temperature components used in various industrial gas turbine engines. The coating process involves codeposition of CrAlY-based particles and a metal matrix of Ni, Co, or (Ni,Co), followed by a diffusion treatment to convert the composite coating to the desired MCrAlY microstructure. Despite the advantages of low cost and non-line-of-sight, this coating process is less known compared to electron beam-physical vapor deposition and thermal spray processes for manufacturing high-temperature coatings. This presentation provides an overview of the electrodeposited MCrAlY coatings for gas turbine applications, highlighting the unique features of this coating process and some important findings in the past 30 years. Recent coating development progress from a collaborative research project between Tennessee Tech University and Oak Ridge National Laboratory will be presented. The effects of additional elements (e.g., Ta, Si and Hf) on the coating oxidation/corrosion performance will be discussed.
