Microstructures within and outside the smear zones for soft clay improvement using PVD only, Vacuum-PVD, Thermo-PVD and Thermo-Vacuum-PVD

Geotextiles and Geomembranes, 2020
Abstract Previous investigators have found increasing rates odf consolidation with increasing degrees of soft clay improvement using PVD only, Vacuum-PVD, Thermo-PVD and Thermo-Vacuum-PVD). This paper utilized scanning electron microscope (SEM) to evaluate and compare the microstructures of the clay specimens obtained from within the smear zone of ...

Study of the wear behaviour of TiAlSiN and TiAlN PVD coated tools on milling operations of pre-hardened tool steel

Wear, 2021
Coatings usually play an important role in terms of machining tool behavior and lifespan. TiAlN is a well-known PVD coating but, the permanent need for improved performance is inducing new compositions around this coating. In this work, the wear behavior

Interface evolution of Si/Mullite/Yb2SiO5 PS-PVD environmental barrier coatings under high temperature

Journal of the European Ceramic Society, 2020
Plasma spray-physical vapor deposition (PS-PVD) was used to prepare tri-layer environmental barrier coatings (EBCs) Si/mullite/Yb2SiO5 on SiCf/SiC substrate. Isothermal oxidation tests of EBCs were performed at 1300 ℃ for 1000 h.

Cavitation erosion of monolayer PVD coatings – An influence of deposition technique on the degradation process

, 2021
TiN, Cr–N, W, WC and WC/a-C: H coatings produced using Physical Vapour Deposition (PVD) method were investigated. TiN and Cr–N coatings were deposited using the cathodic arc evaporation (CAE-PVD) and reactive magnetron sputtering (RMS-PVD) techniques. W,
