Sherardising

    Sherardising is a method of galvanising also called 'vapour galvanising' A layer of zinc is 'applied' to the metal target object by heating the object in an airtight container with zinc powder The temperature that the container reaches doesn't exceed the melting point of zinc Another method of sherardisation is to exppose the intended objects to vapour from molten zinc using a reducing gas to prevent oxidation
    It is ideal for small parts and parts that require coating of inner surfaces such as batches of small items The original system was quite complicated and expensive; however today there are new systems in use which are simple cost effective and relatively environmentally friendly
    For more information on sherardizing you can check BS EN 13811::2003 (this is the British/European Union standard)
