The lifespan of low-carbon steel petroleum pipelines can often be shortened by the erosion–corrosion damage caused their service conditions. Applying electroless Ni-P coating is a promising option to protect from environment due its high hardness and corrosion resistance. However, has low toughness but increased addition NiTi ductile particles. This work produced Ni-P-NiTi coatings different th...

Custom 450 stainless steel and AM 350 are both precipitation hardening steels, which widely used in a variety of aerospace applications. The former exhibits very good corrosion resistance with moderate strength, whereas the latter is for applications requiring high strength along resistance. In this study, behavior CUSTOM steels passivated (a) citric acid (b) nitric solutions 50 75 min at 49 70...

Electrochemical corrosion and passivation characteristics of the oxide dispersion strengthened (ODS) Fe3Al–Ti ODS Fe3Al–Ti–Zr alloys immersed for different exposure times 1, 72, 120, 166 240 h in 3.5 wt % NaCl solution were studied using open-circuit potential, cyclic polarization electrochemical impedance spectroscopy techniques. Both exhibit pitting under chloride ions exposure. In both alloy...

Pitting corrosion is a significant concern for the broader application of stainless steel in modern industries which metal and alloy are detached preferentially from susceptible parts on surface, resulting creation holes passivated alloys that exposed to an aqueous, neutral electrolyte containing corrosive species. Exposure SS brines leads localized loss surface passivity onset isolated pitting...
