“…The intermetallic Ti–Al ordered system is still a topic of extensive study because of its inherent applications for structural materials operating at elevated temperatures [ 6 , 23 , 47 , 53 , 54 , 60 , 69 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 ]. The successful integration of TiAl-based alloys parts into aircraft engines is predicted to tremendously decrease greenhouse gas emission and fuel consumption [ 5 ].…”

The high strength-to-weight ratio property of titanium aluminide (TiAl) based intermetallic alloys makes researchers regard this type of material as a potential replacement for the heavier superalloys of nickel. These alloys have been applied as turbocharger wheels of automobile and turbine blades of aircraft engines. A much recent alloy type of TiAl called the TNM alloy has emerged and primarily amenable to mechanical working; while providing the best combinations of mechanical properties that could be achieved through manufacturing processes with subsequent heat treatments. This is attained by solidifying entirely through the disordered β-phase (A2 structure). Effects of major alloying elements such as strength improvement, microstructural stability and phase formation demand the understanding of these alloying elements addition in TiAl-based intermetallic alloys. This review paper aims at encapsulating several works regarding the effects of major alloying elements on β-solidifying TiAl-based alloys and summarizing the characteristic effects of Si for these types of alloys. An impetus for future works on these types of intermetallic TiAl-based alloys is also presented.

“…Ceramic materials show excellent chemical stability, high hardness and wear resistance, and have higher melting temperature in comparison to other materials [1,2]. Owing to these properties, ceramic materials are employed in various fields such as heat exchangers, motor parts, electrical and electronic components, implants [1], as well as in electrical [3] and power electronic systems [4], as mechanical supports [5], and building-integrated photovoltaics (BIPV) [6].…”

Electrodeposition of ZnO/Cu2O Heterojunctions on Ni-Mo-P Electroless Coating

et al. 2020

Electroless Ni-Mo-P coatings were deposited onto ceramic tiles in order to be employed as electrodes for the electrodeposition of ZnO and Cu2O heterojunction layers. Varying conditions, such as duration, annealing of the electroless coating and applied potential, and duration for ZnO electrodeposition were studied in order to optimize the properties of the ZnO/Cu2O heterojunctions toward improved photoelectrical performance. The coatings were evaluated in terms of morphology, crystalline structure, and by electrochemical and photoelectrical means. The obtained results indicated that a prolonged annealing treatment at low temperature is beneficial to improve the roughness and electrical conductivity of the Ni-Mo-P coating to further enhance the electrodeposition of ZnO. The morphology analysis revealed continuous and homogeneous Ni-Mo-P coatings. The formation of cube-like Cu2O crystals with larger grain size was induced by increasing the deposition duration of ZnO. The properties of ZnO layer are much improved when a higher cathodic potential is applied (−0.8 V) for 1 h, resulting in optimum photoelectric parameters as 1.44 mA·cm−2 for the JSC and 760.23 µV for the VOC value, respectively, for the corresponding heterojunction solar cell.

“…Antiguamente, el término cerámica se utilizaba para todos los materiales hechos a partir de arcilla a elevadas temperaturas. Sin embargo, ahora, un material cerámico es un material que está compuesto por elementos metálicos y no metálicos unidos mediante enlaces iónicos y en menor medida covalentes formando diferentes arreglos estructurales (Kishawy & Hosseini, 2019;Leali & Merolli, 2009).…”

“…Los materiales cerámicos se dividen, principalmente en dos grupos, en cerámicas tradicionales y cerámicas avanzadas (Chatti et al, 2019;Imanaka, 2012;Kishawy & Hosseini, 2019;Leali & Merolli, 2009;Michaelis, 2009;William D. Callister, 2012). Las primeras, cerámicas tradicionales, poseen bajas propiedades mecánicas e incluyen materiales como:…”
