Metal particulates and porous metal media
The porous metal media comprise sintered metal particulates each having a core and a surface, the particulates comprising at least about 60 wt.% of a base metal including at least one of iron and nickel, at least about 11 wt.% chromium and no more than about 0.06 wt.% carbon. The surfaces of the par...

| description | The porous metal media comprise sintered metal particulates each having a core and a surface, the particulates comprising at least about 60 wt.% of a base metal including at least one of iron and nickel, at least about 11 wt.% chromium and no more than about 0.06 wt.% carbon. The surfaces of the particulates are enriched with at least one treatment element in an amount and depth sufficient to enhance the resistance of the particulates to undesirable oxidation. The invention also includes a fine metal filter medium formed from sintered metal fibres, which has enhanced resistance to corrosion and/or to high temperature oxidation. |
