Thick and hard ceramic coatings were fabricated on A356 aluminum alloy by using plasma electrolytic oxidation(PEO) technique.The microstructure and phase compos
A new environmental friendly catalyst, H4SiW12O40/PAn was prepared and identified by means of FT-IR, XRD and TG/DTA. Cyclohexanone 1,2-propanediol ketal was syn
Based on the practical basis of measured activities and phase diagrams as well as in the light of the mass action law, the model of inseparable cations and anio
The effect of post-weld heat treatment on the microstructure characterization of electron beam welded(EBW) joints of Ti3Al-Nb was investigated.The results show
