    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.

    摘要翻译： 本发明提供了一种用于拖车的可伸缩门装置，其包括至少两个挤压铝轨道，每个轨道具有至少一个具有耐磨涂层的引导表面; 以及可滑动地接合到每个轨道的引导表面的门。 耐磨涂层可以包括硬度大于铝的自熔合金，氧化物，碳化物，Al青铜合金或金属陶瓷。 本发明还提供了一种形成用于滑动或卷帘门装置的轨道的方法，包括以下步骤：提供具有至少一个引导表面的铝挤压件，其具有用于接收滚子轴承或滚子的几何形状; 并且在不显着降低铝挤压件的机械性能的温度下在导向表面上形成耐磨涂层。

    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.
