通常，在油砂开采过程中，标准合金不具备在磨损和腐蚀条件下抗磨损性能。对于生产性关键组件，通常采用碳化钨基复合涂层（MMC）来延长设备寿命，防止非计划性停运。复合涂层的性能主要依赖磨损环境。本文将对碳化钨基复合涂层在不同的研磨条件下的机械性能和结构性能进行研究，探讨这种交互作用如何在决定性能等级上起到关键作用。这些信息会为更好的选材提供依据，甚至可延长零部件的寿命。“,”Typically, standard alloys do not have the wear resistance properties necessary to combat the aggressive wearand corrosive conditions prevalent throughout the oil sands miningprocess.For production-critical components, it is common to apply tungsten carbide-based metal matrix composite (WC-MMC) overlays to extend equipment life and prevent unplanned outages. The performance of composite overlays is very much dependent on the wear-environment. This paper will discuss how the interactions between abrasive condition sand the mechanical and structural properties of the WC-MMCs are key in determining the resultant levels of performance. Such information can lead to a better selectionof materials and subsequent extended component life.
