The oxidation of three Fe Cu alloys containing 25,50 and 75 wt% Cu respectively has been studied in air at 600～800℃. The oxidation of all the alloys followed parabolic rate law only approximately and oxidized at the rates lower than those of the two pure

The PU/PTFE abrasion resistant and corrosion resistant composite coating is a new kind of special coating. In the paper the antiwear life and water resistance and the surface structure of the coating were investigated. FTIR, ESCA and SEM analyses showed t

The designing ideas, the structure and the function for a corrosion database system for natural environmental corrosion have been introduced. In this database system, 5 000 000 of corrosion data from various regions all over the country are col

The effect of nitrogen on the intergranular corrosion behaviour of high purity austenitic stainless steel 000Cr19Ni14 has been investigated. The results showed that nitrogen alloying high purity steels exhibited no chromium depletion at grain boundaries a

Some intermetallic phases in Al Li alloy were prepared, and their free corrosion potential and potentiodynamic polarization behaviors in 3.5% NaCl solution were investigated. Experimental results showed that, the corrosion susceptibilities of these phases

7 types of carbonyl derivatives of benzotriazole (BTA) were synthesised by direct reacting BTA with their respective acid chlorides. Their inhibitive properties for copper in 3% NaCl solution were determined using the Differential Pulse Anodic Stripping V

The oxidation behavior of siliconized layer of copper formed by chemical reaction with SiH 4/H 2 mixture was studied.The results show that the formation of silicide layer enhances oxidation resistance of copper. After high temperature oxidation(600℃), a

The resistance of epoxy powder coating and phenolic modified epoxy powder coating to medium permeability has been studied under the static immersion condition. The resistance to cathodic delamination of the coatings has been also investigated. The eff

The sol gel process, which is a new technique of making functional coating at low temperature is reviewed in details. The sol gel coating may particularly be introduced to apply to metal materials for increasing their resistance to corrosion, oxidation, a

A method of measuring and assessing the soil homogeneity was proposed to replace the method of Standard DIN 50929. The index of homogeneity,ΔE(Fe) was defined as the maximum, difference of potentials between two adjacent electrodes, which were inserted

For understanding the behavior of the aging iron artifacts under cathodic protection thick rust layers were prepored on the simulating iron casts and then the effect of the thick rust layers on the behavior of the cast iron under cathodic protection has b

Electrochemical performance of three kinds of Al Zn In alloy anodes have been measured with constant current method,and their microstructures have also been exammed by metallography and scanning electron microscopy (SEM).Results showed that the current ef

Adsorption of cetyl pytidinium chloride (CPC) on aluminium in 0.5 mol/L KCl + 0.5 mol/L HCl solution was studied by electrochemical and SERS methods. It can be drawn that cetyl pytidinium chloride supresses both the anodic and cathodic reactions b

The corrosion performance and inhibition method of pipeline steel in seawater were investigated by potentiodynamic method.One of the main reasons responsible for the corrosion of sea pipeline equipment is oxygen corrosion in sea water. Under the action of

A way of solving hydrogen diffusion equation in the double layer system of hot dip aluminum steel is put forward on the basis of the second Fick diffusion law. Hydrogen diffusion behavior in the system is studied with electrochemical method according to t

The corrosion of butt plates made of A3 steel for precipitators used in a factory for producing alumina is related to an electrochemical process. The corrosion products are mainly Fe 3O 4, Fe 2O 3 and FeO(OH). Water proof measures should be taken

The corrosion inhibitor synthesized from the residual of chemical plant consists of not only imidazolyl amine and naphthenate amine but also other effective compounds, which promotes the synergic effect of corrosion inhibitor.
