    Operation Nickel or the Wankie Campaign or the Wankie Battles was a military operation launched by the Rhodesian Security Forces on 1 August 1967 in response to the group of ZIPRA and Umkhonto we Sizwe (MK) fighters crossing the Zambezi River, which marked the Rhodesian-Zambian border. The operation was a success with only one of the cadres out of a force of seventy-nine making it back to

  • What is Nickel? - Definition from Corrosionpedia

    Nickel also provides reasonable galvanic cathodic protection in the event that mechanical damage to the plating or coating penetrates all the way down to the substrate. The benefits of nickel make it an ideal addition to metal alloys such as nickel-copper, nickel-chromium and nickel-iron. It is estimated that approximately 9% of the total ...

  • Nickel - Wikipedia

    Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer ...

  • Nickel-Based Superalloys - an overview

    Nickel-based superalloys (i.e., Inconel 718, Incoloy 901 and Waspaloy) have been widely employed in the aerospace industry, in particular for the sections of gas turbine engines exposed to great heat. However, they are classified as difficult-to-cut materials due to their high strength, tendency to harden during machining and low thermal conductivity, all of which lead to high temperatures at ...

  • Nickel – the often forgotten battery metal

    Nickel chemicals such as NiSO4 can be manufactured by utilising pure nickel product and dissolving it in acid then crystallising the nickel salt or it can also be manufactured by refining nickel ores and crystallising pure nickel sulphate. The majority of all nickel supplied globally is in the form of NPI or FeNi. This concentration is anticipated to further increase through 2025.
