有兴趣的朋友来翻译一下,比较简单的。最好是语句能组织通顺一点!
When tempering is done immediately after the quenching, the testing may be done after tempering rather than after both quenching and tempering. The heat treater shall maintain average and range or other statistical charts as appropriate for hardness to detect trends in the process and to serve as a quality record. File, Rockwell, or Brinell scale shall be used as indicated on the Engineering Drawing unless the affected Product Engineering Office permits the use of an alternative hardness scale and the change is noted in the control plan. Surface hardness testing with files (refer to SAE J864), where an indentation hardness test is not specified and/or for purposes of correlation, shall only be used if authorized by the affected Ford Supplier Technical Assistance (STA) engineer. When checking the hardness tester with certified blocks the distance between the centers of two adjacent indentations shall be at least three times the diameter of the indentation and the distance to the edge of the test piece shall be at least two and a half times the diameter of the indentation. |
