Complete removal of surface contamination layer of titanium castings
Experiments have confirmed the elevated HF concentration, the reaction is speeded up obviously, and the 0.6MPa pressure blasting test pieces in a concentration of 1mol:5mol mixed acid solution soak for 60sec can be completely remove surface contamination layer.
Therefore, the use of high pressure blast Titanium castings soaked in low concentration of HF and HNO3 mixed acid solution in 60sec can achieve the purpose of complete removal of surface contamination layer.
