Investigation of the properties of a nickel-phosphorous coating in a hydrogen sulfide-containing medium

Progress of electroless amorphous and nanoalloy deposition: a review – Part 1

“…Researchers paid considerable attention to the study of corrosion properties of EPD during this period, with, as a result, many publications in corrosion resistance of EPD produced in these twenty years. [164][165][166][167][168][169][170][171][172][173][174][175] The reasons come from two sides. One is that EPD have few defects such as porosity so that, for a given thickness, their corrosion property is superior to that of electrolytic coatings.…”

“…Another is that the equipment for manufacturing EPD is not complex. The researches not only focused on the corrosion resistance of EN coatings, [164][165][166][167] but also on the corrosion properties of electroless poly-alloys such as Ni-W-P amorphous alloys, 168 and on the corrosion performances of electroless Ni-P composite coatings, such as Ni-P-Si 3 N 4 , 169 Ni-P-polymer (PVC, PVA, PAm), 170 Ni-P-MoS 2 , 171 and Ni-P-TiO 2 . 172 Some groups 173,174 concluded that the corrosion resistance of the electroless Ni-P composite coating was significantly less than that of the electroless Ni-P coatings.…”
