Abrasive wear behaviour of WC-Co and Fe/Cu-based nanostructured coatings has been investigated under dry and slurry conditions in this study. The retention of nanostructured coating constituents was confirmed together with the formation of various metallic and ceramic phases. Abrasive wear rate of nanostructured WC-Co coating was one order lower than that of micro-structured coatings in both conditions. Relatively higher abrasion wear resistance of such coatings compare to reference metallic material was because of comparatively smaller debris formation. These debris roll in between the moving surfaces and thus limit the wear of coating materials. Another aspect of higher abrasive wear resistance is homogeneous distribution of hard (WC and Al₂O₃) particles within relatively soft matrix (Co and FeCu) as revealed by SEM investigation.

在本研究中，已经研究了 WC-Co 和 Fe/Cu 基纳米结构涂层在干燥和浆液条件下的磨料磨损行为。纳米结构涂层成分的保留与各种金属和陶瓷相的形成一起得到证实。在两种条件下，纳米结构 WC-Co 涂层的磨料磨损率都比微结构涂层的磨料磨损率低一个数量级。与参考金属材料相比，这种涂层具有相对较高的耐磨性是因为形成的碎屑相对较小。这些碎屑在移动表面之间滚动，从而限制了涂层材料的磨损。更高耐磨性的另一个方面是硬质（WC 和 Al ₂ O ₃) SEM 研究显示，相对较软的基体（Co 和 FeCu）中的颗粒。
