Cadmium electroplating is widely used in the aerospace industry for the corrosion protection of high strength steels. Cadmium is also used as compatible coating to reduce the galvanic corrosion generated in the assembly ...

The low density and high relative strength of Mg alloys means they can offer engineering benefits over steels or Al alloys. However, the susceptibility of Mg alloys to corrosion has limited their exploitation and restricted ...

An investigation was made into the corrosion of steel immersed in seawater by electrochemical (LPR scans) and weight loss techniques. Steel samples in the form of studs or a specially designed corrosion probe were ...

The hydrogen embrittlement of two HSLA steels was studied in conditions typical of the marine environment. Double cantilever beam specimens, heat treated to produce the microstructure in the heat affected zone of a weld, ...

Passive metals, like stainless steels, are usually protected from corrosion by a thin oxide film on the surface. If the film is stable it will reform spontaneously when it becomes damaged. Erosion-corrosion of passive ...

Aluminium alloys suffer from localised attack termed exfoliation corrosion which is intergranular in nature where the attack proceeds around the elongated grains present in the microstructure. The formation of a more ...

Preferential weld corrosion (PWC) remains a major operational challenge that jeopardizes the integrity of oil and gas production facilities. It is the selective dissolution of metal associated with welds, such that the ...

Slow strain rate tests were performed on quenched and tempered AISI 4340 steel to measure the extent of hydrogen embrittlement caused by electroplating with zincâ  cobalt alloys. The effects of bath composition and ...

300M ultra high strength steel has been widely used for over forty years as a structural material in aerospace applications where a high strength is required. These parts are generally protected from corrosion by electroplated ...

This research project investigates the influence of corrosion flaws on the initiation of fatigue cracks in high strength stainless steels, and more particularly in 15-5 precipitation hardening high strength stainless ...
