Is there any one who can provide some details regarding wear resistance plate (sometime people call compound plate or composite plate) whereby one side of the plate is normal steel plate and another surface is welded with hard facing material (e.g. Chromium carbide materials). Wish to get information about the application of this wear plate in fabricating impeller fan or blower fan blades. Any one has further data or experience, please discussed. Type of joint, Type of weld and type of joining materials to be selected.
