Abstract
PURPOSE: To easily make the sample for microscopic examination easy to discriminated the color of α, β phase etc., by successively treating copper base alloy sampling carried out pretreatment by buffing by etching treatment solution, such as treatment solution of H2O2 etc., acetic acid water solution or sodium thiosulfate water solution etc.
CONSTITUTION: Sample of copper base alloy containing lead, iron etc., is sampled by the cutting process 5 and is finished completely removing minute streak etc. on the surface of microscopic examination by the polishing process 7 after grinding by the grinding process 6. Next, the sample is dipped in treating liquid composed of two component water solution of NH3 and H2O2 in a short time at first and then, yellowish brown thin film on the microscopic examination surface, is removed by dipping in acetic acid water solution and moreover, the sample is dipped in sodium thiosulfate solution at the etching process 8. As a result of it, α phase of the alloy is colored in white, β phase in yellowish brown, Pb grain in black and Fe grain in blue and then, the sample for microscopic examination easy to discriminate added element, is made efficiently in a short time through the drying process 9.
