| 摘 要： | 设计了一种新的测量方法用于测量爆炸喷涂涂层与基体的结合强度，从理论上分析了这种方法拉伸面的临界尺寸，实验结果表明，对国产喷枪尺寸设计为2mm左右是合适的，爆炸喷涂涂层与基体的结合离最高可达143MPa.为避免喷涂过程中金属Co的损失，获得较好的显微形,爆炸气体中C2H2需要过量，O2/C2H2(摩尔比）为1．5左右较合适。

| Abstract: | A new method has been introduced to measure the adhesion strength of the d gun sprayed WC Co coatings The pulling critical size has been analyzed The experiments show that the pulling critical size is about 2mm for detonation spraying gun made in China and the adhesion strength for WC Co coating is as high as 143MPa It has indicated that the value of O 2/C 2H 2 mol ratio must be 1 5 in order to avoid the oxidation of Co during spraying and obtain good microstructure |
