电池锌板XD2是一种较软的材料,在外力作用下易发生范性形变,如制作金相试样时,在切割、磨制、抛光过程中极易产生表面金属变形层,使显微组织呈现假象,影响了检验结果。经反复试验,采用下列制样方法,可消除变形层,得利清晰的组织,见图1、2。 Battery zinc plate XD2 is a softer material, under the action of external force prone to the normal deformation, such as the production of metallographic sample, the cutting, grinding, polishing process is easy to produce surface deformation layer of the metal, the microscopic The organization presents an illusion that affects the test results. After repeated testing, the following sample preparation method, to eliminate the deformation layer, profitably clear organization, see Figure 1,2.
