摘    要:研究开发了一种FeCrBSiMnNbW新型喷涂粉芯丝材,并采用自动化高速电弧喷涂技术在镁合金基体上制备了FecrBsiMnNbw非晶纳米晶涂层。对Fe基非晶纳米晶涂层和传统的3Cr13涂层的组织结构、力学性能以及油润滑条件下的摩擦学性能进行了对比分析,结果表明:与3Cr13涂层相比,铁基非晶纳米晶涂层组织更加致密,孔隙率低,具有相对较高的硬度和拉伸结合强度;形成了非晶相和纳米晶相组成的复合结构,使得涂层具备更好的摩擦学性能。

关 键 词:镁合金  高速电弧喷涂  非晶纳米晶  涂层

Abstract:A new type of FeCrBSiMnNbW spraying cored wire is developed, and the FeCrBSiMnNbW a- morphous and nanocrystalline coating is prepared on substrate of AZ91 magnesium alloy by using an auto- matic high velocity arc spraying technique. The microstructure, mechanical properties and tribology prop- erties under oil lubrication of the Fe-based amorphous and nanocrystalline coating are investigated. The results show that, as compared with 3Cr13 coating, the Fe-based amorphous and nanocrystalline coating is performed with higher micro-hardness and bonding strength, lower porosity, and denser structure. Due to the formation of amorphous and nanocrystalline phase, the FeCrBSiMnNbW coating performs an excel- lent wear resistance.
Keywords:magnesium alloy  high velocity arc spraying  amorphous and nanocrystalline  coating
