用扫描电子正微镜观察20多个失效金刚石拉丝模的模口形貌。
More than 20 pieces of failure wire drawing diamond dies were analyzed by SEM.
该工艺不受人造聚晶金刚石外形及尺寸的限制，可对拉丝模中的人造金刚石聚晶块提供有效的紧固保护。
This technique is no longer restricted by the formal regularity of diamond polycrystal blank, and can give an effective tight protection to diamond polycrystal blank in wire-drawing die.
