Abstract

在不同激光束位姿下进行多个基体倾斜角度(0°、15°、30°、45°)激光熔化沉积试验研究。分析了沉积层外观与形貌特征,以获得两种不同激光束位姿状态下基体倾斜角度对沉积层形貌的影响机制。结果表明:在小倾斜角度(0~30°)范围内,两种激光束位姿沉积层外观质量差距不大;在大倾斜角度(30°以上)范围内,激光束与基体面相对垂直的位姿状态,其沉积层外观质量更好,更有利于界面冶金结合。

Other Abstract

Laser melting deposition experiments of multiple substrate tilt angles (0°, 15°, 30°, 45°) under different laser beam postures were performed. The appearance and morphology of the deposited layers were analyzed to obtain the influence mechanism of the substrate tilt angle on the morphology of the deposited layers under two different laser beam postures. The results show that there is not much difference in the appearance quality of the two laser beam postures at small tilt angles (0°- 30°). But at large tilt angles (> 30°), the posture of the laser beam relatively perpendicular to the substrate surface has better appearance quality of the deposited layer, which is more conducive to the interface metallurgy.
