Effect of boric acid in powder mixed EDM of Ti-6al-4V ELI

WebDuring heating to 400 °C, the raw material can lose as much as 10 wt% volatile mass. With further heating in the presence of oxygen amorphous boron oxidizes to B 2 O 3, and if moisture is present B 2 O 3 can convert to boric acid. Either process leads to conversion of amorphous material and mass gains approaching 130 wt% of the starting sample.
