Problems solved by technology

[0002] The metallographic structure of TC18 titanium alloy is difficult to corrode. Even if it is corroded, its structure is often incomplete. Therefore, the metallographic structure is usually observed by anodic coating and polarized light. At the same time, it is also corroded by some common corrosive solutions. But the effect is not very obvious

Abstract

The invention discloses a TC18 titanium alloy corrosion solution. The corrosion solution is prepared by adding a certain amount of nitric acid, oxalic acid and hydrofluoric acid into distilled water, wherein the volume ratio of hydrofluoric acid, oxalic acid, nitric acid and distilled water is 1: 2.5: 3: 5. During preparation, nitric acid, oxalic acid and hydrofluoric acid are added successively. After TC18 titanium alloy is corroded by the corrosion solution, the crystal boundary and the crystalline grain of the titanium alloy are clearly showed. The corrosion effect is good, the metallographic sample preparation time is greatly shortened, and the corrosion time is short.

Description

technical field [0001] The invention relates to a TC18 titanium alloy corrosion solution and belongs to the technical field of corrosion solutions. Background technique [0002] The metallographic structure of TC18 titanium alloy is difficult to corrode. Even if it is corroded, its structure is often incomplete. Therefore, the metallographic structure is usually observed by anodic coating and polarized light. At the same time, it is also corroded by some common corrosive solutions. But the effect is not very obvious. Therefore, how to make the metallographic corrosion of TC18 titanium alloy simple and fast is a difficult problem to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a TC18 titanium alloy corrosion solution, the grain boundaries and grains of the TC18 titanium alloy after corrosion are clearly displayed, and the corrosion effect is good. [0004] Technical scheme of the present invention:...
