Abstract
A method for making an aluminum substrate that is subjected to repeated impaction more wear resistant. The method comprises applying at least about 0.005 inch thick coating of an amorphous composition directly to only portions of this substrate, preferably after it is shaped into a product for transporting consumable materials. The coating composition to which steel, aluminum, PTFE and/or polyethylene may be added, can be thermally sprayed to the substrate surface.
Claims25
A method for making coated aluminum alloy materials transportation product or stock more wear resistant, said method comprising:
- applying a coating by thermal spraying at least about 0.005 inch thick of an amorphous composition to only certain portions, but not all, of materials-contacting areas of said materials transportation product or stock.
A method for making an aluminum alloy-based, materials transportation product more wear resistant to repeated impaction, said transportation product selected from the group consisting of a dump trailer body, railcar, light truck bed, barge, intermodal container, trash hauler/hopper and a livestock trailer/railcar bed, said method comprising:
- thermally spraying at least about 0.005 inch thick coating of an amorphous composition onto only certain portions, but not all, of the materials-contacting areas for said transportation product, said composition including an iron-based, chromium carbide component.
