摘要
为了研究激光熔覆过程中激光熔池的光谱辐射特性,采用光栅光谱检测技术检测镍硅硼合金粉末熔覆过程中熔池光谱,得到不同功率、速度及时间下的光谱分布。结果表明:激光功率900 W时波长550 nm处熔池光谱相对强度最高为500,功率增加到1000 W时,光谱相对强度增加为600;激光功率保持不变时,光谱辐射相对强度随扫描速度增加而减小,随熔覆过程时间增加而增加,但在15 s后,基本达到稳定状态。激光熔覆过程中熔池光谱波动与熔覆层质量存在一定的关系,试验中发现,功率为900 W,扫描速度2 mm/s时,熔覆层质量较好,试样基体变形较小,熔池光谱相对强度波动也较小。
Abstract
In order to study the spectral radiation characteristics of laser molten pool in laser cladding, grating spectrum detection technology is used to detect the spectrum of molten pool in nickel silicon boron alloy powder laser cladding, spectral distributions in different powers, speed and time are obtained. It is shown that at the wavelength of 550 nm spectrum relative strength is 500 when power is 900 W, and it increases to 600 when power becomes 1000 W, keeping power constant, spectral radiation intensity decreases when scanning speed increases but increases with time and achieves the stable state after 15 s. There is a certain relationship between the quality of laser cladding layers and spectrum fluctuation of molten pool. The results show that when power is 900 W and scanning speed is 2 mm/s, the quality of laser cladding layers is better, the body has small deformation, and the fluctuations spectrum relative strength of the molten pool is relatively little.
