“…In recent years, jet polishing, as an efficient and environmentally friendly surface treatment technique, has been widely adopted in the field of treating various complex workpieces [15][16][17][18][19][20]. Zhao et al [21] combined Taguchi's method with response surface technology to design a rotating jet polishing method, and carried out jet polishing experiments on the inner wall of 304 stainless steel round tubes with a diameter of 50 mm.…”

It is a challenge to polish the interior surface of a small bent pipe with complex structures and sizes less than 0.5 mm. This is because of the fact that traditional polishing methods could destroy, block, or break the small complex structures. For a small bent pipe made of aluminum alloy produced using additive manufacturing, the defects, such as adhered powders and spatters, are easy to jam the pipe without polishing, possibly resulting in catastrophic failure for aerospace applications. To overcome this challenge, a novel water jet polisher was developed using soft polymethyl methacrylate (PMMA) abrasives. After polishing a specific area, the adhered powders on the interior surface were reduced from over 140 to 2, 3, and 6 by the soft abrasives with mesh sizes of 200, 400, and 600, respectively. The surface roughness Sa was decreased from 3.41 to 0.92 μm after polishing using PMMA abrasives with a mesh size of 200. In comparison, silica abrasives were also employed to polish the small bent pipes, leading to the bent part of pipes breaking. However, this kind of failure was absent when using soft abrasives. Computational fluid dynamics calculations elucidate that a peak erosion rate of silica abrasives for a bent pipe with a turn angle of 30° is 2.18 kg/(m2·s), which is 17 times that of soft abrasives. This is why the small bent pipe was broken using silica abrasives, whereas it remained intact when polished with soft abrasives. In addition, water jet polishing has a lower erosion rate, a relatively smooth erosion curve, and less erosion energy, leaving the bent parts intact. The developed soft abrasive water jet polisher and the findings of this study suggest new possibilities for cleaning the adhered powders and spatters and polishing the interior surface of small bent pipes with complex structures.

“…9 Chemical mechanical polishing (CMP) has emerged as the primary processing method for quartz glass due to its high removal rate and low surface roughness. [10][11][12] However, CMP slurry, a crucial material in optical element fabrications, presents distinct challenges. It demands a high level of expertise, involves signicant investment risks, has a lengthy technology accumulation cycle, and relies heavily on economies of scale.…”

“…Currently, the intrinsic threshold of quartz materials can exceed 100 J/cm 2 for samples exposed to ultraviolet laser light. However, when the optical element is exposed to 351 or 355 ns laser light, the surface of the sample is susceptible to nonlinear effects, which can cause the sample to break or incur other damage [6,7]. The primary reasons for these damages are related to the damage precursors generated during the process and the environmental contamination of the sample cleaning.…”

In high-power laser systems, the loading capacity of fused silica components under 351 nm irradiation is an important factor limiting their ability to increase output power, and in the current study, the damage threshold enhancement of fused silica components after RIE and AMP treatments has been investigated. Sub-surface defects in fused silica components after RIE treatment have also been investigated, but the reason for the high damage threshold could never be explained. Since quartz crystals and fused silica belong to the same silica system, and quartz crystals have more characterisation means than fused silica, we can extrapolate to fused silica by studying quartz crystals. We can extrapolate to fused silica by studying quartz crystals, which are characterised by more means than fused silica, and prove that the extrapolation is correct by characterising fused silica. In this study, the relationship between the etching process and the damage threshold is concluded by studying different RIE etching processes, and the damage threshold of the samples is optimal when the etching depth is 1 um.
