一、前言迄今,研究工作者利用高功率密度和短脉冲长度的脉冲激光器在材料表面获得了非晶态组织,但利用连续波Co_2激光器在铁基合金表面获得非晶态组织的工作还未曾开展,本工作对此进行了尝试。试验中,采用高功率连续波Co_2激光器,硼作为合金化元素。这一研究具有极大的工业应用价值,尤其 I. Preface So far, researchers have obtained amorphous structures on the surface of materials using pulsed lasers with high power density and short pulse length. However, the use of continuous wave Co_2 laser to obtain amorphous structure on the surface of iron-based alloys has not yet been carried out This work has been tried. In the experiment, a high power continuous wave Co_2 laser was used with boron as the alloying element. This research has great industrial application value, especially
