| 摘 要： | 本文用正电子湮没技术对等离子体喷涂铜基合金压缩形变的微观缺陷进行了测量。对等离子体喷涂合金，随着压缩量的增加，正电子寿命变短，这一现象与常规合金中观察到的情况相反。

| Abstract: | A positron annihilation technique has been employed to study the microdefects of copper alloy sprayed on a steel substrate by plasma after being compressed in different thickness.The positron lifetime in the alloy is varied with different amount of compression. It is found that the positron lifetime decreases with increasing of the compression deformation. On the contrary, the positron lifetime is increased for normal alloy after deformation. |
