Corrosion Inhibition Efficiency

the corrosion inhibition of polyethylene glycol 200 for magnesium alloy AZ91 in 1% NaCl solution at different temperatures are studied. The morphology of the sample at 25°C is analyzed by SEM. And CHI600C electrochemistry workstation is employed to investigate the corrosion inhibition of the samples. The results show that the corrosion inhibition efficiency of polyethylene glycol 200 to the magnesium alloy AZ91 is affected by temperature. Polyethylene glycol 200 has superior corrosion inhibition to the magnesium alloy at the temperature of 25°C.

This investigation involves the effects of non-ionic surfactant materials on the industrial sodium oleate, sodium naphthenate and their mixtures at different temperatures by the surface tension methods. The effects on the critical micelle concentration (CMC) of sodium oleate were assessed by the Toween 80(T-80) presence, polyethylene glycol, polyether and other non-ionic surfactant. T-80 was proved more effective than other non-surfactant in increasing the sodium oleate CMC at same concentration. Using the optimal composition of sodium fatty acid and the surfactant can reduce the temperature of separation hematite from 43°C to 23°C, achieve the purpose of low carbon and energy saving.
