The composition and structure of substrate materials have important influences on coating performance, especially in terms of bonding strength and coating hardness, which determine whether the coating can be used for a given application. In this study, a TiAlN coating is deposited on Ti(C,N)-based cermet (TC) substrates with 0wt%–20wt% WC by arc io...

The effect of extrusion temperature and ratio on the microstructure, hardness, compression, and corrosion behavior of Mg−5Zn−1.5Y alloy were analyzed in this study. The microstructural observations revealed that the cast alloy consists of α-Mg grains, and Mg3Zn6Y and Mg3Zn3Y2 intermetallic compounds, mostly located on the α-Mg grain boundaries. Ext...

Petroleum coke is industrial solid wastes and its disposal and storage has been a great challenge to the environment. In this study, petroleum coke was utilized as a novel co-reduction reductant of low-grade laterite ore and red mud. A ferronickel product of 1.98wt% nickel and 87.98wt% iron was obtained with 20wt% petroleum coke, when the roasting ...

Combustion kinetics of the hydrochar was investigated using a multi-Gaussian-distributed activation energy model (DAEM) to expand the knowledge on the combustion mechanisms. The results demonstrated that the kinetic parameters calculated by the multi-Gaussian-DAEM accurately represented the experimental conversion rate curves. Overall, the feedstoc...

The interface characteristics of cyanide tailings are different from those of the raw ore. In this study, valuable elements could not be thoroughly recovered via the flotation of cyanide tailings from Shandong, China. The interface and floatability of these tailings were investigated by phase analysis and flotation tests. The chalcopyrite in the cy...

Hexavalent chromium (Cr(VI)) compound is useful to various industries but is toxic and carcinogenic. In this research work, we fabricate an amperometric sensor for the determination of Cr(VI), using a titanium dioxide (TiO2)-reduced graphene oxide (rGO) composite as the sensing element. The composite was synthesized following sol—gel chemistry, yie...

Transition metal phosphides (TMPs) have exhibited decent performance in an oxygen evolution reaction (OER), which is a kinetic bottleneck in many energy storages and conversion systems. Most reported catalysts are composed of three or fewer metallic components. The inherent complexity of multicomponent TMPs with more than four metallic components h...

8-hydroxyquinoline (8-HQ) intercalated layered double hydroxides (LDH) film as underlayer and sol—gel layer was combined for active corrosion protection of the AM60B magnesium alloy. The LDH, LDH/sol—gel, and [email protected]/sol—gel coatings were analyzed using the scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM), ener...

Municipal solid waste incineration products of bottom ash (BA), fly ash (FA), and pickling sludge (PS), causing severe environmental pollution, were transformed into glass ceramic foams with the aid of CaCO3 as a pore-foaming agent during sintering. The effect of the BA/FA mass ratio on the phase composition, pore morphology, pore size distribution...
