At high hardness, therefore, the relationship between Brinell and Vickers or Rockwell scales is affected by the type of ball used.
因此，对于高硬度，布氏硬度计和维氏硬度计或洛氏硬度计的检测值之间的关系就会受到所采用的球体的影响。
2
The wear-resistance, however, tends to increase with the hardness of grinding ball material.
但磨球材质硬度越高，衬板材质耐磨性趋向于增高。
3
Under traditional technique conditions, it is direct proportion that hardness to internal stress, because of inside stress overload, high-Cr grinding ball is failed.
