The aim of this study was to qualitatively demonstrate surface micro-morphological changes after the employment of different surface conditioning methods on high-alumina and glassy-matrix dental ceramics. Three disc-shaped high-alumina specimens (In-Ceram Alumina, INC) and 4 glassy-matrix ceramic specimens (Vitadur Alpha, V) (diameter: 5 mm and height: 5 mm) were manufactured. INC specimens wer...

Thermal barrier coatings (TBCs) are used in gas turbine engines to protect engine hot-section components in the harsh combustion environments, and extend component lifetimes. Infrared Thermography method has been selected for obtaining thermal images and studying the TBCs of Alumina, Zirconia and Alumina+Titanium oxide coated on the base plate of Titanium, by measuring the back wall temperature...

The directional structure of a solution-derived bismuth aluminum gallium tin oxide film is achieved by brush coating method. This used for spontaneous and uniform liquid crystal alignment.

A thin industrial corrosion-protection nanostructured coating for the Al alloy AA2024-T3 is demonstrated. The prepared in a two-step process utilizing hard anodizing as pre-treatment, followed by sealing and atomic layer deposition (ALD). In first step, sulfuric acid at low temperature converts surface into low-porosity anodic oxide. second pores are sealed coated low-temperature ALD using diff...

aluminum alloys such as al 5083 have primary potential for lightweight structural application in automotive and aerospace industries. this paper addresses the mechanical and tribological properties and corrosion resistance of chromium nitride coatings deposited on al 5083 that can be used for development of applications of aluminum 5083 alloy. the crn coatings of 1 μm thickness were deposited b...
