Abstract
Metal products having improved properties and processes for preparing the metal products are provided. The present disclosure provides for a metal product comprising a metal surface, an oxide layer and a glass layer. The glass layer is provided by coating a stable aqueous silicate or borosilicate solution onto the metal surface and curing the aqueous solution to produce a glass layer. The metal products have surface characteristics that outperform all anodized metal surfaces.
Claims11
A layered product comprising:
- a substrate selected from the group consisting of aluminum and an aluminum alloy,
- an anodized-aluminum layer, having a composition that is free of silicates, carried by the substrate;
- wherein the anodized-aluminum layer is a hot-sealed, anodized aluminum layer;
- and
- a silicate glass layer directly carried by the anodized aluminum layer, having a silicate glass layer composition that consists of silicon, oxygen, sodium, lithium and boron.
2 more elements
A layered product comprising:
- a substrate selected from the group consisting of aluminum and an aluminum alloy,
- an anodized-aluminum layer carried by the substrate, the anodized aluminum layer having a non-porous, hot sealed aluminum oxide surface distal from the substrate;
- and
- a borosilicate glass layer directly carried by the non-porous, hot-sealed aluminum oxide surface, having a borosilicate glass layer composition that consists of silicon, oxygen, sodium, lithium and boron.
1 more element
An aluminum part having a corrosion resistant surface;
- the corrosion resistant surface comprising:
- an aluminum or an aluminum alloy surface;
- a hot-sealed, anodized-aluminum layer carried by the aluminum or aluminum alloy surface;
- and
- a borosilicate glass layer carried directly by the hot-sealed, anodized-aluminum layer, having a borosilicate glass layer composition that consists of silicon, oxygen, sodium, lithium and boron;
- and
- wherein the corrosion resistant surface of the aluminum part passes a 2 minute “PH 14 Test” and a “24-hour CASS Test”.
