随着带热障涂层高温合金的广泛应用,对飞秒激光制孔的工艺也提出了更高的挑战,本文通过研究飞秒激光与氧化锆陶瓷的相互作用原理,计算出了当单脉冲能量约为80 µJ时,焦点内的材料可以被完全去除,并通过实验进行了验证。通过大量的优化实验,提出了针对带涂层高温合金的分段制孔法,总结出了最优的工艺参数,可用于任意角度制孔,所获得的微孔涂层表面质量完好,过渡段无裂纹,孔壁质量良好。 |

With the wide application of superalloys with thermal barrier coatings,the process of femtosecond laser hole making has also faced higher challenges. In this paper, by studying the interaction principle of femtosecond laser and zirconia ceramics,the current when the energy of a single pulse is about 80 µJ,the material in the focal point can be completely removed,which is verified by experiments. Through a large number of optimization experiments,a segmented hole making method for coated superalloys is proposed, and the optimal process parameters are summarized, which can be used to make holes at any angle. The surface quality of the obtained microporous coating is intact and the transition section cracks and has no hole wall quality is good. |
