| 摘 要： | 介绍一种新型电弧喷涂技术--粉末复合电弧喷涂技术。运用粉末复合电弧喷涂技术对轴类零件和轴承座内孔进行喷涂。在喷涂前，对轴类零件粗车螺纹并进行挤压，使基体表面形成钩子形状，增加喷涂层和基体的机械结合力；对轴承座内孔进行堆焊，将大表面分割成小表面，减少了喷涂层收缩时形成的裂纹，提高了喷涂层与基体的结合强度。这两种方法适合大型轴类零件的表面强化和修复。

| Abstract: | A new technology-the electric arc spraying technology combined by powder is introduced. Using it to spray on axes and bore of bearing. Before spraying, the axes are turned out screw thread and extruded, thus many hooks are arranged on the surface of parts, it strengthens the mechanical combination of spraying layer and substrate; Bead inside bore of bearing, the large surface is divided into several small ones, the number of flaws are decreased and the bond strength of spraying layer and substrate is strengthened. These two methods can be used to strengthen and repair surface for large-scale axis parts and bore of bearing. |
