Their success depends on the proper engineering and design of size, alloy, and material hardness.
垫片和密封圈的成功使用取决于其尺寸、合金材料及材料硬度的正确选择及设计。

The composition was optimized by tiny alloying, orthogonal test design and the hardness and impact toughness test for the different samples with different combination of alloy composition.
The correct engineering concept should be using a correct composition design method to further raise the toughness under the prerequisite of obtaining a high hardness.
