抗冲击磨损奥氏体堆焊材料

Impact wear-resistant hardfacing austenitic material

    摘要
  • 摘要: 针对具有冲击磨粒磨损工况条件,成功研制出了一种奥氏体堆焊材料EKCM50。该堆焊材料为Fe-Mn-Cr-Mo-V合金系,通过耐磨性对比试验分析,堆焊合金耐磨性能优于D256焊接材料。经过加工硬化冲击试验,EKCM50焊接材料堆焊层硬度由32HRC升高到45HRC,经过冲击磨损试验,40min后,试验材料堆焊磨损失重几乎不变。通过对该材料的加工硬化和磨损性能的试验研究,探讨了此种奥氏体材料的加工硬化及耐磨机理,以及加入的合金元素对该焊接材料的耐磨性及耐磨机理的影响规律。

     

    Abstract: One kind of hardfacing austenitic electrode for impact wear resistance,named EKCM50,which is a Fe Mn Cr Mo V alloy system,was developed.Experiments and analysis show that the wear resistance properties of the deposited metal are higher than that of the D256 electrode.After work hardening impact experiments,the hardness of EKCM50 bead weld layer increases from 32HRC to 45HRC.After 40 min of impact wear experiments,the weight loss of deposited metal is very slight.The mechanism of strain hardening and wear resistance of welding material,and the influence of these alloying elements on wear resistance was discussed.
