Aluminide coating is prepared on K438 Ni-based superalloy by pack cementation. The hot corrosion test of as-received and pre-oxidation aluminide in Na 2 SO 4 salt are carried out at 1050°C. morphologies, phase composition, products characterized XRD, SEM, EDS, TEM. conclusion that the has excellent properties. After corrosion, oxide scale thinnest maintains good integrity. However, fluctuates g...

With good mechanical properties and corrosion-resistance, galvanized coils are used in many fields nowadays, such as auto industry and household appliance industry. Because of high additional value of galvanized product, steel plants pay much more attention on how to make continuous galvanizing lines (CGL) run efficiently. In this paper, we address a scheduling problem of continuous galvanizing...

During the operation of overhead conductors, conductors are corroded to varying degrees by smoke and dust, harmful gases from factories around lines, or in corrosive salt fog atmosphere coastal island areas, as well humid hot weather conditions. In this paper, through study corrosion mechanism conductor, types analyzed, factors leading process analyzed selecting steel cored aluminum stranded wi...

Metallic materials will continue to have challenges related fracture, transcrystalline, and hydrogen embrittlement corrosion due severe area of application that is unavoidable. The study into the performance metallic has shown mechanism through stress cracking often occurs vis-viz electrochemical reduction reaction. phase diagram important solve problems hot corrosion, embrittlement, intergranu...
