Inhibitive effect of Xylopia ferruginea extract on the corrosion of mild steel in 1M HCl medium

The alkaloid content of the leaves and stem bark of Xylopia ferruginea plant was isolated and tested for its anticorrosion potential on mild steel corrosion in a hydrochloric acid medium by using electrochemical impedance spectroscopy,potentiodynamic polarization measurement,scanning electron microscopy(SEM),and Fourier transform infra red(FTIR) analysis.The experimental results reveal the effective anticorrosion potential of the plant extract.The mixed mode of action exhibited by the plant extract is evidenced from the polarization study.SEM images proof the formation of a protective layer over the mild steel surface,and this is supported by the FTIR study.The possible mode of the corrosion inhibition mechanism has also been discussed.     

Effects of sample width on flame spread over horizontal charring solid surfaces on a plateau

Experiments were conducted on the Tibetan Plateau to investigate the effects of sample width (W) on flame spread over horizontal charring solid surfaces. The results show that the rate of spread is influenced by the combined effects of convection heat transfer and flame radiation. Moreover, two different regimes depending on sample width were found in flame spread behavior. The rate of spread decreased with width in the convective regime (W≤3 cm) but increased in the radiative regime (W>3 cm). Similar results were observed in comparative experiments conducted on a plain in Hefei, with the rate of spread reaching its minimum value at W=4 cm rather than 3 cm.
