ABSTRACT MgAl LDHs intercalated with CO(NH 2 ) 2 , NH 4 Cl and NH 3 ·H 2 O were prepared by co-precipitation and XRD, FT-IR, TGA-DTA and SEM techniques were employed for characterization. The results indicated that the layer-layer spacing of LDHs was enlarged by 0.169, 0.285 and 0.227 Å with the intercalation of CO(NH 2 ) 2 , NH + 4 and NH 3 , separately. The effects on thermal stability and degradation behavior of synthesized LDHs where mole ratios...

ABSTRACT The thermal stability of nanocrystalline Ni-Co-Fe-P coatings with phosphorus content up to 3.38 wt% prepared by pulsed electrodepostion was studied using XRD, TEM and DSC. It is found that multi-component alloying does improve the thermal stability of nanocrystalline coatings due to a “solution drag effect”. For nanocrystalline Ni-40.41%Co-6.16%Fe-1.63%P coating, P-atoms ...
