  • Study of Optical and Electrical Properties of Nickel Oxide

    25/10/2014· Nickel oxide thin films were prepared by spraying a 0.1 M solution of nickel nitrate of doubly distilled water onto the pre-heated amorphous glass substrates kept at 390˚C ± 10˚C. Film thickness was measured by using the weight difference method considering the density of the bulk nickel

  • How to Troubleshoot and Fix Nickel Show from Hex-Chrome

    17/09/2020· Regular Hull cell analysis is also essential to indicate if nickel show is due to a chemical imbalance in either the nickel or chrome plating baths. Most decorative hex-chrome electrolytes should cover 60-75% of a 3-minute, 5-amp Hull cell panel from left to right. If the chromic acid concentration is adequately high but poor coverage is still evident, then a reduction of the sulfate ion via

  • Kinetics of nickel particle formation on silicon substrate

    18/03/2020· Formation of nanosized nickel particles is performed by 'Nanofab 800 Agile' by Oxford Instruments. The nickel film is aged at the temperature of 880 °C for 1, 3, 10 and 30 min. After ageing, the film interface is analysed by atomic-force microscope (AFM). The nickel film distribution obtained by AFM for all samples is shown in figures 1(a)–.

  • Analytical and electrochemical study of passive films

    The critical [Crib concentration necessary to reach a substantial and protective C r 2 0 3 barrier at the film/oxide interface is roughly the same but the film thickness in Ni-Cr alloys is reduced by a factor 2 (15 to 20 monolayers, i.e. about 3.5 to 5 nm) (Table 1). In fact, in those passive layers which contain mostly Crox species with about the same amounts as in the Fe-Cr alloys, the

  • Product Focus – Nickel 200/201

    As such, one thing that Nickel 201 is known for is its use in the caustic alkali concentration (chloralkali) process, which spans many industries. This process produces chlorine and sodium hydroxide (caustic soda), and the whole workflow is highly corrosive. With an unrivalled resistance to caustic alkalies, Nickel 200 is a popular material of choice to manufacture cathode elements. Nickel 200

  • Study of the processing properties of a nickel-based

    The diamond-blade array is made by depositing a nickel-based diamond film onto a disk tool (substrate) through electrochemical co-deposition. The nickel-diamond wheel blank is then cut using RWEDM (Rotary Wire Electrical Discharge Machining) to produce a multi grinding-edge array from the blank. The developed diamond-blade array is then employed in machining a microgroove array on NAK80 steel
