“…Stalin et al [18] examined the hardness behavior of AA7072-MoO 3 composites and stated that addition of MoO 3 reinforcement improves the hardness of the composites. FenWang et al [19] investigated the mechanical behavior of Ti-Al-TiO 2 -MoO 3 composites and reported that adding of MoO 3 rises the mechanical properties of the composites. Arun Premnath et al [20] utilized pin on disc instrument to study the wear properties of carbon fiber nano SiC composites and GRA combined with Taguchi technique was utilized to find the finest process parameters.…”

Molybdenum Trioxide (MoO3) has received extensive consideration as a prospective reinforcement for metal matrix composites (MMCs) to improve the properties. The goal of this work is to fabricate and examine the properties of AA5083-MoO3 composites. AA5083-MoO3 composites by several weight percentages were produced via liquid metallurgy technique. The compositions of the composites are AA5083, AA5083-4wt.%MoO3, AA5083-8wt.%MoO3 and AA5083-12wt.%MoO3. The microstructure inspection was made on the synthesized AA5083-MoO3 composites using Scanning Electron Microscope (SEM). The effect of MoO3 weight percentage on the properties such as density, porosity, mechanical and wear behavior were investigated. The SEM images expose the even dispersion of MoO3 particles with AA5083 matrix. The combination of MoO3 particles enhanced the properties of the composites. The wear behavior was examined via pin on disc apparatus at various process parameters wt.%, load, sliding velocity (V) and sliding distance. Trials were conducted as per L16 orthogonal array (OA). Optimum process parameters to acquire least wear rate and co-efficient of friction (COF) was done by Grey Relational Analysis (GRA). The ANOVA results exposes that wt.% is the major important parameter inducing wear and COF.

“…In the feng wang research, composite (Ti,Mo)Al/Al2O3 was successfully synthesized by hot pressing based on the Ti-Al-TiO2-MoO3 system where in-situ hot pressing utilizes low energy requirement, contaminant-free and stable interface and chemistry, which can overcome this weakness TiAl based alloys and improve in-service properties of the TiAl composite [70]. Figure 1 shows a schematic illustration hot pressing process for glass-ceramics.…”

Ceramics globally has been developed by various materials and methods to find suitable ceramics for specific applications. This paper discusses development of several methods in ceramic preparation such as hot-pressing, sintering, co-precipitation, and solid-state method. In 2001 up to 2019, hot-pressing method was used to manufacture ceramic B4C and SiAlCO as raw material doping by (W, Ti)C. In 2002 up to 2018 sintering method by using fly ash as raw material with an additional K2CO3, Na2CO3, and Nb2O5. In 2008, co-precipitation method was used for CaCu3Ti4O12 (CCTO) as raw material until 2019, and then ZrO2-Al2O3 as a newcomer ceramic material. From 2001 up to 2017, solid-state method was used with microwave for MgTiO and 3-CaTiO with Eu and (Lu, Gd) 2O3 as a dopant. This paper provided four methods and the materials from reported references from 2000 up to now, as guidance in producing specific functional ceramics in the future.

“…Various transition metals such as molybdenum (Mo), titanium (Ti), aluminium (Al), vanadium (V), nickel (Ni), and niobium (Nb) [13][14][15][16][17][18] have been extensively studied for their electrochromic (EC) performance. On the other hand, rare earth metal elements such as dysprosium (Dy), lanthanum (La), yttrium (Y), erbium (Er) [19][20][21] have proven their potential as dopants for enhancing photocatalytic activity. However, only a few of these, such as cerium (Ce) and gadolinium (Gd) have been the focus of studies on overall EC performance.…”
