“…In addition, the laser-remelted coating exhibited better thermal shock resistance than plasma sprayed coating. Duran et al [26] evaluated the wear and corrosion of flame sprayed Al 2 O 3 -TiO 2 coating on AISI 1020 carbon steel. The electrochemical techniques (Tafel) were used to estimate the resistance against corrosion.…”

The current work evaluates the effect of hot corrosion on ASTM-SA213-T-22 Steel with a coating of 100Al 2 O 3 and 20TiO 2 -Al 2 O 3 at 900°C in the molten salt environment of (Na 2 SO 4 -60% V 2 O 5 ). The coatings were sprayed by plasma spray technique. The bare and coated samples were placed inside the muffle furnace at 900°C for 50 cycles. Each cycle consisted of heating for 1 h and 20 min of cooling at ambient temperature. The kinetics of hot corrosion was analyzed by measuring mass gain after each cycle. The results were achieved by using visual examination, mass change measurement, XRD and SEM/EDS analysis. The result revealed that bare steel was more affected with corrosion and gained more mass due to the development of iron oxide (Fe 2 O 3 ) than the coated sample. Fe 2 O 3 and Cr 2 O 3 were found as major phase in oxide scale of T-22 uncoated steel specimen. The 100Al 2 O 3 and 20TiO 2 -Al 2 O 3 coated specimen indicated the reduction in mass gain by 25.41% and 67.02% respectively as compared to uncoated specimen. Al 2 O 3 coating with the combination of TiO 2 showed better adhesion properties. The presence of TiO 2 enhanced the durability and strength of Al 2 O 3 coating to withstand high temperatures.

“…Typical applications for such CMCs are crucibles, nozzles, tubes, thermocouples, and coatings (for thermal corrosion and wear protection) [62]. Researchers have studied the characterization of Al 2 O 3 coatings with the addition of TiO 2 , as well as the effects of TiO 2 in addition to alumina base plasma sprayed coatings concluding that titanium dioxide lowered the microhardness of the alumina coating [18].…”

Ceramic matrix materials have attracted great attention from researchers and industry due to their material properties. When used in engineering systems, and especially in aero-engine applications, they can result in reduced weight, higher temperature capability, and/or reduced cooling needs, each of which increases efficiency. This is where high-temperature ceramics have made considerable progress, and ceramic matrix composites (CMCs) are in the foreground. CMCs are classified into non-oxide and oxide-based ones. Both families have material types that have a high potential for use in high-temperature propulsion applications. The oxide materials discussed will focus on alumina and aluminosilicate/mullite base material families, whereas for non-oxides, carbon, silicon carbide, titanium carbide, and tungsten carbide CMC material families will be discussed and analyzed. Typical oxide-based ones are composed of an oxide fiber and oxide matrix (Ox-Ox). Some of the most common oxide subcategories are alumina, beryllia, ceria, and zirconia ceramics. On the other hand, the largest number of non-oxides are technical ceramics that are classified as inorganic, non-metallic materials. The most well-known non-oxide subcategories are carbides, borides, nitrides, and silicides. These matrix composites are used, for example, in combustion liners of gas turbine engines and exhaust nozzles. Until now, a thorough study on the available oxide and non-oxide-based CMCs for such applications has not been presented. This paper will focus on assessing a literature survey of the available oxide and non-oxide ceramic matrix composite materials in terms of mechanical and thermal properties, as well as the classification and fabrication methods of those CMCs. The available manufacturing and fabrication processes are reviewed and compared. Finally, the paper presents a research and development roadmap for increasing the maturity of these materials allowing for the wider adoption of aero-engine applications.
