This research unravels the formation mechanism of a hybrid conversion treatment including well-established Zr coating with silane-based organic additive and Cu-based inorganic additive. The deposition this was investigated on thermal oxide film Advanced High Strength Stainless Steels (AHSSS). has been characterized using advanced surface analytical techniques such as XPS, FEG-AES, GDOES, ToF-SI...

This study aims to investigate the improvement of tribocorrosion properties WC-TiC-Co substrates by coating them with hard coatings such as AlCrSiN using cathodic arc deposition. is commonly used in fabrication machining and cutting tools; however, there are some materials titanium or stainless steel that difficult work with; furthermore, aggressive environments under high temperatures performa...

The rapid inward migration of fluoride ions in growing anodic titanium oxide under a high electric field has been elucidated by anodizing a Ti-12 at% silicon alloy, where film growth proceeds at nearly 100% efficiency in selected electrolytes. Further, incorporated silicon species in the anodic film are immobile, acting as marker species. The migration rate of fluoride ions is determined precis...

As a complementary method to RBS, GDOES (Glow Discharge Optical Emission Spectrometry) was used to investigate the depth profiles of W, Mo, Be, O and C concentrations into marker coatings (CFC/Mo/W/Mo/W) and the substrate of divertor tiles up to a depth of about 100 m. A number of 10 samples cored from particular areas of the divertor tiles were analyzed. The results presented in this paper ar...

In this study, the cerium-doped hydroxyapatite (Ca10−xCex(PO4)6(OH)2 with xCe = 0.1, 10Ce-HAp) coatings obtained by spin coating method were presented for first time. The stability of 10Ce-HAp suspension particles used in preparation was evaluated ultrasonic studies, transmission electron microscopy (TEM), X-ray diffraction (XRD), and scanning (SEM). surface morphology studied SEM atomic force ...

Modern medicine is still struggling to find new and more effective methods for fighting off viruses, bacteria and fungi. Among the most dangerous and at times life-threatening fungi is Candida albicans. Our work is focused on surface and structural characterization of hydroxyapatite, silver doped hydroxyapatite and zinc doped hydroxyapatite deposited on a titanium substrate previously coated wi...
