A typical structure of thermal spray coatings consisted molten particles, semi-molten oxides, pores, and cracks. These factors caused the porosity sprayed coatings, leading to a significant influence on coating properties, especially their wear-corrosion resistance. In this study, post-spray sealing treatment Cr3C2-NiCr/Al2O3-TiO2 plasma-sprayed was carried out, then, corrosion properties were ...

In dieser Studie wird die Entwicklung verschiedener thermisch gespritzter Beschichtungen für den Einsatz im Armaturenbau diskutiert. Basierend auf etablierten Verschleißschutzschichten der Armaturenindustrie wurden verschiedene Festschmierstoffe in diese integriert, um das Verschleiß- und Reibungsverhalten bei anwendungsnahen Belastungen Armaturen zu verbessern. Für Anwendungen Basis von WC/CoC...

In this study, commercial-grade NiCr (80 wt % Ni, 20 wt % Cr) and NiCrSi (55 wt % Ni, 40 wt % Cr, 5 wt % Si) were used as targets and the sputtering method was used to deposit NiCr and NiCrSi thin films on Al₂O₃ and Si substrates at room temperature under different deposition time. X-ray diffraction patterns showed that the NiCr and NiCrSi thin films were amorphous phase, and the field-effect s...

Wear resistant coatings that comply with non-toxic environment goals are highly desirable. Cr 3 C 2 –NiCr is a promising alternative to the toxic, ‘Co’- containing WC–Co mitigate wear. The purpose of this study was examine suitability for automotive brake disc application by systematically investigating their dry sliding wear behavior at different test conditions. Therefore, High Velocity Air F...

NiCr₂O₄ as a potential protection for thermal barrier coatings (TBCs) against the attack of molten calcium-magnesium-alumino-silicate (CMAS) was studied by a CMAS-contacting experiment. Atmospheric plasma sprayed coatings and sintered bulk materials were fabricated, covered with CMAS deposits, and exposed to 1200 °C for 24 h. Nano-sized CMAS-NiCr₂O₄ mixed powder was manufactured by ball milling...

BACKGROUND It has been suggested that inaccuracies in cancer registries are distorting UK survival statistics. This study compared the Northern Ireland Cancer Registry (NICR) database of living patients, with independent data held by Northern Ireland's General Practitioners (GPs) to compare and validate the recorded diagnoses and dates held by the registry. METHODS All 387 GP practice manager...
