Pickling of titanium
WebbPickling rate of Ti6Al4V HF+20% HNO 3 solution for 30 minutes The influence of the hydrofluoric acid (HF) in 20% (volume) of nitric acid (HNO 3 ) is shown in the Figure 8. The pickling rate of Ti-6Al-4V in 20% volume of HNO , for 30 minutes, increases as the volume percent of HF increases. Webb30 sep. 2014 · Pickling is also used to remove surface contamination from some components. For example, stainless steel or titanium fabrications can be pickled to remove traces of steel from their surface, which can cause problems in later processing or might provide an initiation site for a corrosion problem.
