Chemical Milling - an overview | ScienceDirect Topics

Chemical milling process is generally carried out in a series of five steps: cleaning, masking, scribing, etching, and demasking [10]. Fig. 5.1.4 represents the schematic diagram of chemical milling process. At first, the workpiece surface is cleaned properly for removing the contaminants which could negatively impact the quality of the finished part.

The Largest Cost Reduction Opportunity for Titanium

milling, often in conjunction with HF -HNO 3 pickling, must follow each hot working step. Surface metal is removed down to the bottom of the deepest cooling cracks, resulting in yield loss of approximately 4% to 7% per conditioning step. If the cracks are not fully ground or machined away, they could propagate during the next hot or cold working/processing step, contributing to even greater

Comparative Behavior of Titanium and Zirconium in

The different behavior of titanium and zirconium in HF-HNO 3 pickling solutions has been studied using electrochemical methods and Raman spectrometry. In each case, the depleting of the solutions during a pickling experiment could be correlated with the consumption of HF to form metal oxo or oxofluoro complexes. However, the mechanism of metal dissolution is quite different for the two metals
