The surface topographies of stainless steel in an early stage of pitting corrosion were imaged by a home made electrochemical scanning tunneling microscope (ECSTM). The influences of potential, chloride and time on the surface topographics were examined i

The electrochemical behavior of Aluminum in 0.5mol/L NaCl solution was studied by potentiodynamic method and potentiostatic hydrogen gathering measurement. When high hydrogen evolution overpotential metal ion In3+ was added in the solution , the active

The surface profile and the potential difference distributions over welded stainless steels were measured by using scanning Kelvin probe technigue.A good relation was found between the potential distributon and the corrosion behavior of the specimens expo

In this paper the classification of corrosion factors and the selection of key parameters in corrosion modeling were studied. Based on the correlation coefficient matrix recreated from original data set, the classification diagram of corrosion factors wa

The effect of polarization and frequency on the crack propagation behavior including crack propagation rate(CPR) and fracture surface was studied. The results showed that in A537/3.5%NaCl active system CPR increased with the decrease of frequency under s

Seven pure Mannich bases were synthesized, their corrosion inhibition for 20# carbon steel in 1 mol/L HCl solution was examined by using weight loss, polarization resistance and polarization curve measurements. The effect of the chemical structure of Ma

The susceptibility to intergranular corrosion of 304L austenitic stainless steel was studied by CPE (constant potential etching) method. Then the results of CPE method were varified by EPR (electrochemical potential kineti

Adsorption behaviors of thiourea and urea at the silver electrode in sulphuric acid solution were investigated using polarization curves and Raman spectroscopy. It was shown that thiourea took part in the reaction of anodic dissolution of siver,and

The results of research on inhibitors and their action mechanisms in recent years were reviewed. The following aspects were mainly discussed: the inhibitive action mechanism of inhibitors for SCC, the inhibitive action of thiourea and its derivatives, cin

By measuring pipeline to soil potential,potential gradient and stray current direction, an investigation of stray current on an oil pipeline showed that the stray current interference was very large. Therefore, a sacrificial anode drainage was applied

The seawater cooler of a exhaust silencer was manufactured with 316L stainless steel and protected with zinc alloy sacrificial anodes . The potential distribution of the cooler and the weightloss of the sacrificial anodes were determined on a 1∶1 model wh
