Special Issue Information

Dear Colleagues,

Metallic coatings are primarily fabricated through the deposition of powders layer by layer onto a substrate using various spraying processes. They are widely used as a functional surface modification to protect the underlying substrate from damage under corrosion, erosion, high-temperature, and other aggressive environments. The emerging additive manufacturing processes can be utilised in a similar manner. Typically, these processes will build 3D components with geometric precision by direct material deposition onto a substrate or alternatively by selectively melting material layer by layer on a powder bed. Additive manufacturing offers flexibility in geometric design, rapid production of components with complex geometry and high spatial resolution, and customization of products at an acceptable cost, and has little material waste through the recycling of unprocessed powder. Today, with the rapid development of modern industry and the launch of industry 4.0, high value-added components that are difficult to produce using conventional manufacturing processes are in great demand; this is particularly the case within cutting-edge fields such as the aerospace, nuclear, and energy industry. Since novel metallic coating and additive manufacturing techniques will be critical to future developments within these industries and many others, this Special Issue is dedicated to the recent advances in metallic coating and, in particular, additive manufacturing technologies and the transition between the two. Original research and critical review articles in the relevant topics are welcomed.

In particular, the topics of interest include, but are not limited to:

  • Thermal spray, cold spray, laser cladding, PVD, CVD, and other coating technologies
  • Selective laser melting, laser metal deposition, electron beam melting, and other additive manufacturing processes
  • Numerical modelling on melting pool, material deposition, and manufacturing processes
  • New coating, additive manufacturing, and 3D printing technologies
  • Applications and case studies of additive manufacturing and 3D printing technologies

Yttria-stabilized zirconia (YSZ) hollow sphere (HS) powder is a novel potential feedstock material for the plasma spraying of next generation advanced thermal barrier coatings with low thermal conductivity and high sintering resistibility. In this study, YSZ HS powders were prepared by plasma treatment with/without a heat preservation zone around the flying path of the particles during plasma flame. The results of the scanning electron microscopy of YSZ HS powders showed that HS prepared with a heat preservation zone during the plasma process exhibited a regular spherical morphology and a homogeneous thin shell structure. Due to the sufficient heating of the shell regions, the HS powder presented a well densified shell structure. Furthermore, the mechanism of formation of the HS powder with reduced shell thickness was also discussed based on the analysis of the evolution of the powder structure. This kind of hollow sphere powder with a very thin shell structure provides a new alternative feedstock material for the development of next generation high performance thermal barrier coatings.
