Investigation of carrier transport in ZnO and ZnO:Al thin films sputtered at different oxygen conditions

Undoped and doped zinc oxide in film form is used in a wide range of applications. Its electrical and optical properties depend on the oxide conditions during preparation, which are influenced by many deposition parameters. The aim of this work was to experimentally investigate...

Changes in Structure and Corrosion Resistance of Cryogenically Treated WC-Co Cemented Carbides

Deep cryogenic treatment (DCT) of WC-Co cemented carbides (CC) was experimentally explored. Four types of cemented carbides were studied. They had different WC grain sizes and the volume fractions of the cobalt binder. Some specimens were deep-cryogenic-treated (DCT) at -186°C in dry va...

Surface Pretreatments of AA5083 Aluminum Alloy with Enhanced Corrosion Protection for Cerium-Based Conversion Coatings Application: Combined Experimental and Computational Analysis

The effects of surface pretreatments on the cerium-based conversion coating applied on an AA5083 aluminum alloy were investigated using a combination of scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), polarization testing, and electrochemical impedance spectroscopy. Two steps...
