Method of removing an alpha-case titanium layer from a beta-phase titanium alloy

摘要

A method of surface treating a metallic article (10) includes the step of chemically removing a surface layer (12) having titanium alloy alpha-phase precipitation to expose a core (14) having titanium alloy beta-phase. In one example, the chemical removal includes using a first solution having nitric acid and hydrofluoric acid, and a second solution having nitric acid.
