Abstract:

PURPOSE: To obtain the method of manufacturing a test piece capable of generally and commonly applying the alloy of a zirconium group and reducing the manday of manufacture.

CONSTITUTION: A test piece is manufactured in the following condition. A polishing condition is Ra<0.22 and Rmax<1.16. In an etching condition etching is performed for 10-30 seconds by means of a reagent for corrosion containing hydrofluoric acid, nitric acid and glyceline. The concentration ratio of the reagent for corrosion indicates that hydrofluoric acid and nitric acid arc within a full line sounded by A-F and the residual is glyceline. The etching is again performed for 3-15 seconds by means of nitric acid solution in which the concentration of nitric acid contains 52.5vol% or more after the etching as after treatment.
