磨损

Through the failure analysis of tamping pick and abrasion contrast test, we select the fit pickax shoe wearable material; through the welding and performance test, we set about from selecting welding rod and establishing welded craft with reason to judge whether the welding between the pickax shoe wearable material which we have selected and the pickax body material or not?

通过对捣镐的失效分析和磨损对比试验，选择合适的镐靴耐磨材料；通过焊接及焊后的性能试验，从合理选择焊接材料和制定焊接工艺着手，判断所选镐靴耐磨材料与镐体材料之间的焊接是否可行？

Apply the metalloscope, the scanning electric mirrorand energy spectrum analysis instrument etc. material analysis way and MLD-10 dynamic load abrasion tester, JB-36 three use the impact tester etc. test equipment to analysis and test the wearable performance of selected material and welding quality of welding sample. So as to make certain the best welding material and welding crafts between the welding of pickax boot wearable material and pickax body material in making tamping pick adopting parted type structure.

应用金相显微镜、扫描电镜、能谱仪等材料分析手段以及MLD-10动载磨料磨损试验机、JB-36型三用冲击试验机等试验设备，对所选材料的耐磨性能和焊接试件的焊接质量进行分析测试，以确定分体式结构制造捣镐的工艺中最佳镐靴耐磨材料及其与镐体材料捍接过程中的最佳焊接材料和焊接工艺。

The result of abrasion test and welding tests show, the crafts of adopting parted type structure to make tamping pick is viable theoretically, the pickax boot wearable material we have selected havent appear brittleness desquamation under the condition of test, and the ratio of performance and price of the material is higher; The welding joint has no obvious welding bug under the condition of test, the break mode of welding slot metal is mainly toughness break, and the craft performance of the weld material we have selected is all right, the welding craft we have established is suitable to the occasion and feasible.

磨损试验和焊接试验结果表明，采用分式体结构制造捣镐这一工艺理论上是可行的，所选镐靴耐磨材料在试验条件下未见脆性剥落，而且性价比较高；焊接接头在试验条件下没有明显的焊接缺陷，焊缝金属断裂方式主要是韧性断裂，而且所选焊接材料工艺性能良好，所制定焊接工艺切实可行。
