    摘要: The present invention provides a retractable door apparatus for trailer trucks including at least two tracks of extruded aluminum each having at least one guide surface with a wear resistant coating; and a door in slideable engagement to the guide surfaces of each track. The wear resistant coating may include a self fluxing alloy, oxide, carbide, Al bronze alloy, or cermet having a hardness greater than aluminum. The present invention also provides a method of forming the tracks for the sliding or rolling door apparatus including the steps of providing an aluminum extrusion having at least one guide surface with a geometry for accepting a roller bearing or rollers; and forming the wear resistant coating on the guide surfaces at a temperature that does not substantially reduce the mechanical properties of the aluminum extrusion.

    摘要: A spacer member for supporting a metallic alloy product during heat treatment comprising a ceramic core and a tubular housing is disclosed. The tubular housing, which encloses the ceramic core, comprises a bore, a wall portion, and two end portions. In order to resist deformation during usage, the tubular housing is made from high temperature steel, a high temperature steel alloy, or cold rolled steel. The wall portion has at least two substantially flat surfaces having corner edges that have a radius of at least ⅜ inch and ends that are tapered at least ¼ inch. In addition, the flat surfaces also have a coating that reduces the sticking of a metallic alloy product. The end portions each have at least one aperture to allow the inside to adjust itself to ambient atmospheric pressure. A method of making a spacer member is also disclosed.
