Laser cladding of transparent fused silica glass using sub-µm powder

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 additive through laser cladding. Laser cladding of transparent fused was achieved using CO 2 -laser locally melt substrate while injecting stream fumed powder into melt-pool. By described technique, it possible manufacture fully sintered with deposition rate up 29 mm 3 /min. In this work we have studied dynamics influence different process parameters on final quality.
