The currents of cathodic protection(CP) sysytem were analysed into several parts, namely: currents along the protected equipments; currents from anodes to ground; and currents from ground to protected equipments. According to the electric field theory of

A new type of thermal barrier coating is being developed for aircraft gas turbine blades by laser cladding on superalloy substrates. During rapid melting and solidification in laser processing, an oriented epitaxial growth, closely packed columnar structu

The electrochemical corrosion behaviour of electroless amorphous Ni P coating/carbon steel substrate and electro deposited nanocrystalline Ni coating/carbon steel substrate were studied by linear polarization, potentiostatic curve and AC impe

The sputtered LDZ125 coating producted by planar magnetron sputtering technique has homogeneous structure and very fine grain size(less than 100 nm) consisting of γ phase, while the cast alloy is composed of γ,γ' and carbides. The cyclic oxidation resista

The electrochemical impedance spectroscopy of carbon steel in flowing 3.5% NaCl solution was studied. The experimental results showed that: the Nyquist plots for carbon steel in flowing single or double phase solution were single capacitive loops. With i

The behavior of galvanic corrosion between graphite/epoxy conposites(GECM)and metals(LD10,YLD10,H62,1Cr18Ni9Ti) at different temperatures (28℃,35℃,45℃,65℃) was evaluated by galvanic couple tests for 30 days. Results indicated that significant galvanic cor

The performance of conversion films containing rare earth element on aluminum and its alloys has been studied by linear polarization technique,polarization curve measuring,and neutral salt spray test.The test results revealed that: the uniform corrosion r

The corrosion resistance of Ti biomedical materials in body fluids was reviewed. The main corrosion types including local corrosion, fretting corrosion, corrosion fatigue and stress corrosion cracking were introduced. It was showed that the titanium and t

IrO 2 SnO 2/Ti and IrO 2 PdO x SnO 2/Ti electrodes were made by the thermal decomposition technique in air. The electrochemical behaviors of the anodes were studied by polarization curves,cyclic voltammetry curves and electrolytical experimentation in fre

The stray current corrosion of buried water pipeline of a plant at Anshan was prospected and analyzed. The direct electrical drainage protection and cathodic protection methods were designed . During 6 years in service , it was found that the united prote

316L stainless steel is a kind of material with good corrosion resistance, but its properties of anti SCC are considerably affected by assembling quality, especially by welding quality. The failure on the heat affected zone (HAZ) in a 316L stainless stee
