Effect of electrolytic nickel coating on fatigue life of iron based powder metal parts
(2011)
Electrolytic coating is one of the methods mainly used to provide corrosion resistance for the powder metal parts. The coatings have strong effects on mechanical properties of coated parts as well as on surface properties. ...
The thermodynamic stability of intermediate solid solutions in LiFePO4 nanoparticles
(Royal Society of Chemistry, 2016)
Theoretical predictions from first principles and recent advances in in situ electrochemical characterization techniques have confirmed the presence of solid-solution states during electrochemical (de)lithiation of LiFePO4 ...
Particle-size and morphology dependence of the preferred interface orientation in LiFePO4 nano-particles
(Royal Society of Chemistry, 2014)
We gain new insights into the equilibrium properties and potential two-phase lithiation mechanisms in LiFePO4 nano-particles by conducting a first-principles investigation of the anisotropic chemical interfacial energy ...
Fully reacted high strength geopolymer made with diatomite as a fumed silica alternative
(Elsevier Ltd, 2017)
Geopolymers are formed by mixing of aluminosilicate sources with alkaline meta-silicate solution at room temperature. In the current study, diatomite of Turkish origin was fully utilized as a fumed silica alternative for ...
The effect of anodization parameters on the formation of nanoporous TiO2 layers and their photocatalytic activities
(Elsevier B.V., 2014)
In this work, nanoporous titanium dioxide (TiO2) layers were successfully formed by electrochemical anodization method on titanium (Ti) surface in fluorine containing electrolytes with different processing parameters. The ...
Abrasive wear, structure, and mechanical aspects of Al–Al2O3 composites fabricated using various mixing media during P/M routes
(Springer New York LLC, 2016)
The effects of mixing method during powder metallurgy (PM) routes on the abrasive wear behavior of Al–Al2O3p composite materials is investigated. For this purpose, starting Al powders with a constant volume fraction of 10% ...
Effects of nitridation time and precursor particle size on yield of β-SiAlON synthesized from calcined kaolinite
(Springer New York LLC, 2019)
Carbothermal reduction and simultaneous nitriding (CTRN) of natural aluminosilicates is a method used to obtain phases of Si–Al–O–N system. SiAlON phases have important applications, such as high technology ceramics, for ...
