| 軸承磁粉探傷時(shí)實(shí)物試塊與A型試片的關(guān)系(35 卷) |
| 英文標(biāo)題 |
| The Relationship Between Actual Calibration Block and A-type of Calibration Piece During the Magnetic Powder Flaw Detection on Bearings |
| 摘要 |
| 目前，國內(nèi)磁粉探傷常用A型靈敏度試片的顯示來表征探傷系統(tǒng)靈敏度，衡量磁化工藝參數(shù)。經(jīng)試驗(yàn)，機(jī)車車輛軸承磁粉探傷時(shí)，由于軸承鋼具有高矯頑力，靈敏度試片只能顯示磁場方向，不能真實(shí)反映磁化工藝參數(shù)，應(yīng)采用實(shí)物試塊。 |
