以17CrNiMo6鋼滲碳齒輪為例,首先制備了不同程度的磨削燒傷試樣，并依據(jù)酸洗法和金相法對(duì)其進(jìn)行磨削燒傷級(jí)別分類;然后通過建立不同磨削燒傷級(jí)別齒面磁彈法所測特征值MP與其表層顯微硬度、殘余應(yīng)力的對(duì)應(yīng)關(guān)系曲線，驗(yàn)證了磁彈法能夠?qū)B碳齒輪的磨削燒傷做出準(zhǔn)確評(píng)價(jià)，并使用該方法對(duì)不同磨削燒傷等級(jí)進(jìn)行了量化表征。在此基礎(chǔ)上，將磁彈法檢測納入實(shí)際生產(chǎn)檢驗(yàn)流程中，實(shí)現(xiàn)了滲碳齒輪磨削燒傷的在線檢測。

With 17CrNiMo6 steel carburized gears as example, firstly different degree of grinding burn test samples were prepared, and the grinding burn grade of these samples was classified by pickling method and metallographic method. Then by establishing the corresponding relationship curves between magnetoelastic characteristic values MP and the tooth surface micro-hardness or residual stress of the carburized gear samples with different grinding burn grade, it was verified that the magnetoelastic method could be used to accurately assess the grinding burn grade of carburized gears. Besides, by magnetoelastic method the grinding burn grade could be expressed quantitatively. On this basis, by introducing magnetoelastic method into the practical production inspection process, grinding burn online detecting of carburized gears was realized.
