Through analysis and tests, the authors selected corrosion resistant nitrogen case-hardening process to replace chrome plating.

通过分析和试验，我们采用了抗蚀渗氮取代电镀铬工艺。

This impervious layer or boundary will retard the free diffusion of moisture. This condition is referred to as case hardening.

这一不透气的壳层(或边界层)会阻滞水分自由扩散，这种情形称为表面硬化。

The hardening case depth and hardness curve can be changed by adjusting heating time, heating power and cooling speed during induction hardening.

在感应淬火中，通过改变加热时间、加热功率和冷却速度可以改变淬硬层深度和硬度梯度。

The procedures of heat treatment of steel include hardening tempering annealing and case hardening.

钢的热处理工序包括硬化、回火、退火和表面硬化。

This use case is one of the cornerstones of basic WebSphere MQ administrative hardening.

此用例是基本WebSphere MQ管理的基石。
