Abstract
The invention provides a metallographic corrosion method of a Ti-Ag alloy and the Ti-Ag alloy, and relates to the technical field of metallographic detection. The metallographic corrosion method comprises the following steps: machining Ti-Ag alloy so as to form a microscopic structure observation plane on the Ti-Ag alloy; the microscopic structure observation plane is ground on a metallographic phase pre-grinding machine, and the ground microscopic structure observation plane is placed on a polishing machine to be subjected to mechanical polishing; etching the mechanically polished microscopic structure observation plane by using an etchant solution to obtain a microscopic structure observation plane to be observed; wherein the corrosion solution comprises ammonium hydrogen fluoride, hydrofluoric acid and water, and the ratio of the ammonium hydrogen fluoride to the hydrofluoric acid to the water is (5-10) g: (10-20) mL: 100 mL. According to the method, the metallographic corrosion effect of the Ti-Ag alloy can be improved.
