Fused silica glass is a commonly used high-performance material. However, due to the high temperature necessary for its production, manufacturing can also be challenging and costly. An attractive approach is additive manufacturing through laser cladding. Laser cladding of transparent fused silica was achieved using a CO₂-laser to locally melt the substrate while injecting a stream of fumed silica glass powder into the melt-pool. By the described technique, it is possible to manufacture fully sintered silica glass with deposition rate up to 29 mm³/min. In this work we have studied deposition dynamics and influence of different process parameters on the final deposition quality.

使用亚微米粉末激光熔覆透明熔融石英玻璃

熔融石英玻璃是一种常用的高性能材料。然而，由于其生产所需的高温，制造也可能具有挑战性且成本高昂。一种有吸引力的方法是通过激光熔覆进行增材制造。透明熔融石英的激光熔覆是使用 CO ₂激光器局部熔化基板，同时将气相二氧化硅玻璃粉末流注入熔池来实现的。通过所描述的技术，可以制造沉积速率高达29mm ³ /min的完全烧结的石英玻璃。在这项工作中，我们研究了沉积动力学和不同工艺参数对最终沉积质量的影响。
