为研究硬质合金顶锤在线检测功能,使用万能压力实验机对已开裂的硬质合金顶锤进行重复压力实验,并同时使用声发射检测仪检测。通过对实验数据的分析变换,获得了已开裂顶锤声发射信号基本特征。结果表明:硬质合金顶锤材料符合费利西蒂、反凯赛尔效应,其在工作过程产生的开裂信号能够被声发射检测仪发现并检测,声发射在线检测具有可行性。
為研究硬質閤金頂錘在線檢測功能,使用萬能壓力實驗機對已開裂的硬質閤金頂錘進行重複壓力實驗,併同時使用聲髮射檢測儀檢測。通過對實驗數據的分析變換,穫得瞭已開裂頂錘聲髮射信號基本特徵。結果錶明:硬質閤金頂錘材料符閤費利西蒂、反凱賽爾效應,其在工作過程產生的開裂信號能夠被聲髮射檢測儀髮現併檢測,聲髮射在線檢測具有可行性。
