抗冲击耐磨损堆焊材料的耐磨行为

为研究高性能的抗冲击耐磨损堆焊材料，在大量实验的基础上，成功研制出了综合性能优良的抗冲击耐磨损堆焊材料——焊条TKCE50.经过对制备的试样分别进行多次冲击磨损试验，并与D256焊条进行对比试验，分析试样的硬度和磨损失重变化，结果表明， 此种堆焊材料具有焊接工艺性好、堆焊层组织加工硬化率高和耐凿削式冲击磨损性能优异的特点.通过对该堆焊材料堆焊层的加工硬化和磨损性能及其机理的试验研究,探讨了该种堆焊材料的加工硬化及耐磨机理.

Wear resistant behavior of deposit material with impact wear-resistance

To enhance the impact wear-resistant performance of deposit material,a new surfacing electrode,TKCE50,has been successfully developed based on a great amount of experiments.The impact abrasion tests were performed,and both hardness and wear loss of the samples were compared with classical surfacing electrode D256.The results indicate that the developed surfacing electrode has not only good welding technological properties,but also super work-hardening effect and good impact wear-resistance.In addition,the work-hardening and wear-resistant mechanisms for this electrode have been discussed based on the corresponding experimental investigation and theoretical analysis.
