YG8

Shape retention of YG8 and J12 thin bar cemented carbides in practical production were analyzed and several methods were brought out to prevent deformation .

从毛坯厚度差、装舟方式、冷却速度、舟皿涂料等方面分析了YG8和J12硬质合金长条薄片的弯曲变形原因，提出了几种抑制弯曲变形的措施。

Cobalt phase was chemically etched to certain depth beneath the surface and porous layer was formed after YG8 cemented carbide had been soaked in aqueous solution of dilute nitric acid .

YG8硬质合金经稀硝酸水溶液化学侵蚀后，表面一定深度内的粘结相钴将被化学刻蚀掉，引起表层疏松。

Friction wear behavior both in air or in N 2 atmosphere at different temperature ranging from 200 ℃ to 800 ℃ was studied for Al 2O 3 / TiB 2 ceramic composite against cemented carbide ( YG8 ) .

研究了Al2O3／TiB2陶瓷材料与硬质合金往复滑动摩擦时，在不同气氛和温度条件下的摩擦磨损特性。
