Loading effect etching
Witryna負載效應（loading effect）可以分為3種：巨觀負載效應（macroloading）、微觀負載效應（microloading）以及與與刻蝕深寬比相關的負載效應（aspect ratio dependent etching，ARDE）三種效應圖解說明如圖1所示。所謂巨觀負載效應，是因刻蝕總面積的增加而導致的整體刻蝕速率下降，如圖1（a）所示。 WitrynaTherefore, it is believed that the bias power had a greater effect on the etch rate. In Figure 7(c), only the bias power voltage is considered to see the bias power effect. ... C. J.

Witryna10 kwi 2024 · Because the use of hydrofluoric acid (HF) poses health risks if handled improperly, many clinicians prefer to have the ceramic restorations pre-etched in dental laboratories. However, during the try-in procedure, the pre-etched glass–ceramic restorations may be contaminated with saliva resulting in reduced bond strength. This …
