摘要
采用CO2激光器在316L不锈钢表面获得了超薄的铜熔覆层。文中分析和讨论了激光熔覆工艺参数如激光功率、熔覆速度、离焦量以及送粉率等对熔覆层质量的影响,提出了熔覆工艺的优化方法,使铜层的熔覆厚度可控制在100μm之内。
An investigation is underway to assess thin copper cladding on substrate of 316L stainless steel by CW CO2 laser.This perliminary work analyses some special features of the cladding process,provides a basic information about the relationship between the parameters of cladding processing and the quality of cladding layer.The influences of cladding condition,such as laser power,beam travelling speed,defocusing distance as well as power flow rate,on copper layer are also discussed in this paper.The main achievement of this investigation is the fact that a thin copper layer can be obtained on the substrate,with thickness smaller than 100 μm,dilution lower than 10% and few thermal distortion .
