The new concept of thermal barrier coatings with Pt + Pd/Zr/Hf-modified aluminide bond coat and ceramic layer formed by PS-PVD method

open access: yesHigh Temperature Materials and Processes, 2021
Thermal barrier coatings (TBCs) are widely used for protection of gas turbine parts from high temperature and corrosion. In the present study, the new concept of TBCs with three-element-modified aluminide coatings was presented.

Erosion, corrosion and erosion-corrosion of EB PVD thermal barrier coatings [PDF]

open access: yes, 2008
Electron beam (EB) physical vapour deposited (PVD) thermal barrier coatings (TBCs) have been used in gas turbine engines for a number of years. The primary mode of failure is attributed to oxidation of the bond coat and growth of the thermally grown ...

Erosion of gadolinia doped EB-PVD TBCs [PDF]

open access: yes, 2006
Gadolinia additions have been shown to significantly reduce the thermal conductivity of EB-PVD TBCs. The aim of this paper is to further the understanding on the effects of dopants on the erosion resistance of EB-PVD TBCs by studying the effects of 2 ...

Nano and Micro indentation studies of bulk zirconia and EB PVD TBCs [PDF]

open access: yes, 2004
In order to model the erosion of a material it is necessary to know the material properties of both the impacting particles as well as the target. In the case of electron beam (EB) physical vapour deposited(PVD) thermal barrier coatings (TBCs) the ...

Damage Accumulation Phenomena in Multilayer (TiAlCrSiY)N/(TiAlCr)N, Monolayer (TiAlCrSiY)N Coatings and Silicon upon Deformation by Cyclic Nanoindentation

open access: yesNanomaterials, 2022
The micromechanism of the low-cycle fatigue of mono- and multilayer PVD coatings on cutting tools was investigated. Multilayer nanolaminate (TiAlCrSiY)N/(TiAlCr)N and monolayer (TiAlCrSiY)N PVD coatings were deposited on the cemented carbide ball nose ...

Effect of microstructure and temperature on the erosion rates and mechanisms of modified EB PVD TBCs [PDF]

open access: yes, 2009
Thermal barrier coatings (TBCs) have now been used in gas turbine engines for a number of decades and are now considered to be an accepted technology. As there is a constant drive to increase the turbine entry temperature, in order to increase engine ...

Direct Processing of PVD Hard Coatings via Focused Ion Beam Milling for Microinjection Molding

open access: yesMicromachines, 2023
Hard coatings can be applied onto microstructured molds to influence wear, form filling and demolding behaviors in microinjection molding. As an alternative to this conventional manufacturing procedure, “direct processing” of physical-vapor-deposited ...

Characterisation of PVD-TiN coated austempered ductile iron: Effects of nodule count and austempering temperature [PDF]

open access: yes, 2011
In this work PVD-TiN coatings are deposited on ADI substrates austempered at 280 and 360°C, with nodule counts varying between 490 and 1 100 nod/mm2. The deposition is performed at 300°C by the arc ion plating technique.
