Multilayer chromium based coatings grown by atmospheric pressure direct liquid injection CVD [PDF]

open access: yes, 2009
There is a great interest for multilayer hard coatings because they exhibit enhanced properties resulting from their nanostructuration. Such coatings are frequently constituted of carbide and nitride and are generally deposited under very low pressure by

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 ...

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 ...

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.

Study on wear behaviour characteristics of ZrO2 and ZrN coated AZ91D Mg alloy [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2023
The as-received AZ91D Mg alloy was coated with ZrO2 and ZrN ceramics using the Physical Vapour Deposition (PVD) process. Dry sliding wear investigations were performed in a pin-on-disc wear tester at a sliding velocity of 2-8 m/s and a normal load of 2 ...
