| 摘 要： | 以一种多元素铁基合金粉芯丝材(含Fe,Cr,B,Ti,C,Mo等)作为堆焊材料,用CO2气体保护焊堆焊的方法在基体A3钢上制备涂层。用X-射线衍射仪检测涂层的晶体结构,DSC分析非晶的起始晶化温度;透射电镜观察涂层的微观组织结构,扫描电镜观察涂层的形貌,并利用显微硬度仪和高温摩擦磨损试验机分别测量涂层的显微硬度和耐磨损性能。结果表明:所制备的涂层均匀致密,与基体结合良好;涂层含有非晶并且非晶的起始晶化温度约为524℃;这种非晶涂层具有较高的硬度和很好的耐磨损性能,近表面的最高硬度达825 HV0.3,耐磨性是A3钢的5.9倍.

| Abstract: | An iron based powder consisting of Fe,Cr,B,Ti,C,Mo and so on was welded onto A3 steel substrate using CO2 welding to create an amorphous coating.Crystal structure of the coating was studied by XRD,the original crystallization temperature was found via DSC,the microstructure was studied through TEM,the topography of the coatings was observed by SEM and the microhardness and wear resistance were measured using a microhardness tester and a high temperature abrasion machine respectively.The results show that th... |
