摘要
使用HSC 31快速扫描红外热像仪 ,测量了含Al2 O3 表层的锌铝合金激光熔覆时的表面温度场 ,测得熔池中最高温度为 16 72℃ ,边缘温度为 6 0 0～ 70 0℃ ,冷却速率为 2× 10 3 ～ 3× 10 4 ℃ /s以及熔池形状和等温曲线。
The measurements of the surface temperature fields of laser re-melting area in the Zn-Al based ceramic thin film, scanning heating by CO 2 laser, were carried out with an HSC-31 fast-scanning infrared thermovision. The center and edge temperatures of melting pool, and the isotherms of different temperatures, and the shape of the melting pool were measured.
