Surface characterisation studies of nickel-chromium PVD: EB evaporated low carbon steel samples

摘要: AbstractIncreasing concern over toxic wastes produced by nickel–chromium (Ni–Cr) plating industries has resulted in strong research efforts to replace conventional physical vapour deposition techniques like evaporation and sputtering. Ni–Cr coatings on mild steel substrates an electron beam process with layer thickness of ∼8–10 m have been investigated regard the structural corrosion properties. The structure coating was evaluated X-ray diffractometer (XRD). (110) Cr (200) Ni predominant peaks crystallite size range 25–30 nm observed from XRD pattern. electrochemical polarisation studies performed samples showed resistant nature evaporated underlayer substrates. Atomic force microscopy (AFM) scanning (SEM) were used investigate surface characteristics before after tests. loc...
