ABSTRACT:
This application describes a composition and a process of chemically milling refractory metals and their alloys. The composition comprises a combination of nitric acid, hydrofluoric acid, and phosphoric acid, and preferably includes a derivative of carbonic acid, such as carbamide. The composition is particularly useful in the chemical milling of beta titanium, alpha beta titanium, and alpha titanium alloys. Use of the composition of this invention results in reduced tolerances in the chemically milled article and also reduced hydrogen absorption in the titanium part which is chemically milled.
