abstract

  • A simple, one-step slurry coating technique was used to aluminize open cell nickel metal foam at low temperature and short hold-down time. Three slurries of different composition, heat-treated at 650 °C for 2 h,
    were used to investigate the possibility of developing an aluminide
    coating on a commercially produced Ni foam. In all cases a dense,
    well-adhered to the Ni substrate aluminide coating of several mum
    thickness was produced. The thickness and aluminide phase and
    composition (NiAl and/or Ni3Al) of the coating strongly depend on Al content and the mix of activators in the slurry.
