Abstract
Official abstract text for this publication.
The present disclosure is directed to a metal-containing apparatus including a substrate member constructed of a metal that is highly resistant to pitting corrosion and wear in aggressive media. An exemplary metal-containing apparatus is a plate heat exchanger. The metal includes an oxidation layer on the surface thereof and a thin metal oxide nanoporous film on top of the oxidation layer. The nanoporous film is highly compliant and is comprised of oxygen and aluminum, titanium, silicon, zirconium and combinations thereof.
First claim
Opening claim text (preview).
We claim: 1. A heat exchanger comprising: a substrate member constructed of a metal, wherein the metal is selected from the group consisting of stainless steel, black rebar, carbon steel, and aluminum; an oxidized layer on a surface of the substrate member, wherein the oxidized layer has a thickness of less than 100 nanometers; and a first nanoporous film comprising titanium dioxide and silicon dioxide, the nanoporous film being chemically bonded to the oxidized layer, the nanoporo…
