金属基复合材料是应用前景广阔的工程结构材料，其表面加1的方法有两种：一种是热喷涂，用于预成形；另一种是喷镀，用于特制加工以满足材料表面耐磨的需要。美国马萨诸塞州的Avco特种材料公司研究出了一种钎焊团结预成形制造方法，其过程如下：将碳化硅纤维缠绕在一个固定的支 Metal-matrix composites are promising engineering structural materials. There are two ways to add 1 to the surface: one is thermal spraying for pre-forming and the other is thermal spraying for special processing to meet the requirements of material surface resistance Mill needs. Avco Specialty Materials of Massachusetts, USA, has developed a method for the fabrication of a brazed joint. The process is as follows: The silicon carbide fiber is wound around a fixed branch
