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...

XRD Analysis of Tungsten Carbides with Cobalt Binder

The paper deals with the influence of deep cryogenic treatment on the structure of sintered WC-Co carbides from the aspect of XRD analysis. We demonstrate the influence of cryogenic processing on the change of grain size, the development of Co phases in the structure, and ...
