The application of a bipolar electrochemistry technique to simulate the galvanic corrosion behaviour dissimilar stainless steels is introduced. allows comparison response by controlling extent localised as function an applied offset potential. setup was explored performance type 420 ferritic and 304L austenitic steels, yielding information about anodic vs. cathodic these materials when in close...

The effects of the electrogalvanizing conditions (a combination plating current and time) on hydrogen infusion, embrittlement, corrosion-induced embrittlement (HE) behaviors ultra-high strength steel were examined. A range experimental analytical methods, including electrochemical impedance spectroscopy, permeation, polarization, slow strain rate test, employed. results showed that applied cath...

Friction stir welding (FSW) is a solid-state joining method that suitable for dissimilar materials such as aluminum and steel due to its comparatively low process temperatures. Such hybrid joints are of great interest in view lightweight construction efforts various industrial sectors transportation. As the combination different metals structures may cause corrosion problems area because format...

Host-guest inclusion complexes are abundant in molecular systems and of fundamental importance in living organisms. Realizing a colloidal analogue of a molecular dynamic inclusion complex is challenging because inorganic nanoparticles (NPs) with a well-defined cavity and portal are difficult to synthesize in high yield and with good structural fidelity. Herein, a generic strategy towards the fa...

Two kinds of CoCrNi composite coatings, CoCrNiMo and CoCrNiMoBC, were prepared by laser cladding on the base metal 304 stainless steel. The wear corrosion properties coatings studied tests electrochemical tests. Results show that addition B4C promotes generation ceramic phase, therefore improving microhardness coating enhancing its resistance, while simutaneously keeps excellent resistance. Ene...

Recent research has focused on rehabilhation and strengthening of steel structures and bridges using fiber reinforced polymer (FRP) materials. The bond behavior of FRP materials to steel structures is quite different from lhat of concrete structures. Preliminary test results showed the occurrence of very high bond stresses for most strengthening applications due to the amount of strengthening r...

The overly-fast degradation rates of magnesium-based alloys in the biological environment have limited their applications as biodegradable bone implants. In this study, rare earth element yttrium (Y) was introduced into AZ61 magnesium alloy (Mg-6Al-1Zn wt %) to control the degradation rate by laser rapid melting. The results showed that the degradation rate of AZ61 magnesium alloy was slowed do...

Fracture failure of super 13Cr can occur in complex and harsh environments such as high temperature, pressure, corrosive gas wells, which damages the economic benefit oil development also poses a great threat to wellbore integrity. Therefore, it is urgent study corrosion mechanism tubing this performed an on-site experimental analysis on failed tubing, employing microarea electrochemical scanni...
