一、前言液体渗铝是将工件浸入熔融铝液中,使铝原子渗入工件表面,从而形成铝铁合金涂层的一种化学热处理方法。卧式浸铝炉一般采用槽式熔铝容器,立式浸铝炉一般采用坩埚式熔铝容器,其材料有的选用石墨、陶瓷等非金属材料,有的选用碳素钢、合金铸铁等铁基金属材料,由于前者强度低,导热性能差,大型容器制作困难,大规模生产应
First, the preface Liquid aluminum is the workpiece immersed in the molten aluminum solution, so that aluminum atoms penetrate the surface of the workpiece, forming a ferrous alloy coating a chemical heat treatment method. Horizontal dip-aluminum furnace generally used trough aluminum container, vertical dipping furnace crucible-type aluminum container, some of its material selection of graphite, ceramics and other non-metallic materials, and some use carbon steel, alloy cast iron and other iron Base metal materials, due to the former low strength, poor thermal conductivity, large-scale container manufacturing difficulties, large-scale production should be
