Formation of ceramic alumina nanocomposite coatings on aluminium for enhanced corrosion resistance

Effects of Al2O3 coating on diesel engine performance, combustion, and emission characteristics fueled by pongamia methyl ester and its blends with diesel

“…Plasma spray technology has the advantage of being able to process low-grade-ore minerals to produce value-added products, and also to deposit ceramics, metals and a combination of these, generating homogenous coatings with the desired microstructure on a range of substrate [23][24][25]. A nano ceramic material of Al 2 O 3 used in this work was obtained from USA.…”

An investigation of the characteristics of Al2O3/TiO2 PEO nanocomposite coating

“…This phenomenon formed pan-like and crater features and left some pores on the samples surface [22,23,33,34]. It is believed that the current density and the treatment time of PEO process can mostly determine the coating quality [23,29]. As can be seen in Fig.…”

“…It has been reported that the high localized temperature of the discharges melts aluminum and oxidizes it to alumina in the molten state due to exposure to electrolyte [1]. This molten alumina phase can react with silicate ions present in the electrolyte, forming alumina-silicate phases as Mullite [29]. The presence of TiO 2 peaks can be attributed to nanoparticles embedded in the mentioned phase.…”

Environmental friendly anodizing of AZ91D magnesium alloy in alkaline borate–benzoate electrolyte

“…Vigorous sparking and gas evolvement at excessive high current density often result in poor anodized coating [24][25][26][27], while too low anodizing current density will make the formation of anodized films unachievable [28].…”
