求翻译：Photograph of a steel gear that has been “case hardened.” The outer surface layer was selectively hardened by a high-temperature heat treatment during which carbon from the sur- rounding atmosphere diffused into the surface. The “case” appears as the dark outer rim of that segment of the gear that has been sectioned. A是什么意思？ 待解决

照片已被一个钢齿轮的“表面硬化”的外表面层，选择性地由高温热处理硬化期间碳从外加的舍入大气扩散到表面。

是“案件钢齿轮的照片硬化了”。期间从环绕大气的苏尔的碳散开入表面的高温热治疗选择性地硬化外表面层数在。“案件”出现作为齿轮的那段黑暗的外面外缘被区分了。实际尺寸。(表面分部内地罗斯照片礼貌。)

照片的钢制齿轮已"硬的案"。外表面层选择性是通过在其中碳从苏尔-舍入大气扩散到表面耐高温热处理硬化的。作为那段已经被切齿轮的黑暗外缘出现"案"。实际大小。（照片由表面司米德兰 － 罗斯）。
