5%ITP(中间转变产物)的深度如何掌握?按什么标准?
我有一个相关标准,但没有关于中间转变产物深度的明确规定,原文为:
The visual estimated depth to 5% intermediate products should be, at a minimum, 50% of the effective case measurement on a gear pitch line or shaft diameter.
For gear roots, the visual estimated depth to 5% intermediate products should be, at a minimum, 25% of the effective case depth measurement of the gear root.(可参考以下链接http://www.rclbbs.com/redirect.p ... o=lastpost#lastpost)
应如何翻译?
但在另一处有如下条文Alloy Oxidation/Depletion - Surface oxidation products and surface intermediate products should not exceed a depth of 0.025mm。
是按0.025mm吗? |
