Abstract

Ocean engineering components are subjected to intense corrosion and abrasion. To address these challenges, the Fe-based amorphous composite coating was engineered for compatibility with these harsh conditions. The Fe-based amorphous composite coating, incorporating TiN_x, demonstrated improved nanomechanical properties, offering enhanced resistance against external forces. The integration of TiN_x acted as a structural backbone, limiting crack propagation within the amorphous matrix. Although the corrosion resistance of this composite coating was slightly reduced, it demonstrated improved durability subjected to hydraulic machinery corrosion abrasion working condition. Notably, under conditions of higher tribological pair speeds and increased sand concentrations, this composite coating exhibited significantly lower weight loss increase and reduced wear rates escalation compared to coatings made entirely from Fe-based amorphous material. Moreover, the composite coating exhibited diminished susceptibility to erosion damage, with reduced size and severity of erosion craters. These underlying mechanisms are thoroughly discussed in the paper.

通过反应等离子喷涂将 TiNx 集成到铁基非晶涂层中，改善多尺度机械性能和耐腐蚀性-耐磨性

海洋工程部件经受着强烈的腐蚀和磨损。为了应对这些挑战，我们设计了铁基非晶复合涂层，以适应这些恶劣条件。含 TiN 的铁基无定形复合涂层具有更好的纳米机械性能，可增强抗外力的能力。TiN 的加入起到了结构骨架的作用，限制了裂纹在非晶基体中的扩展。虽然这种复合涂层的耐腐蚀性略有降低，但在液压机械腐蚀磨损的工作条件下，其耐久性得到了提高。值得注意的是，与完全由铁基无定形材料制成的涂层相比，在摩擦副速度较高和砂浓度增加的条件下，这种复合涂层的重量损失增加明显较低，磨损率上升也有所降低。此外，复合涂层对侵蚀破坏的敏感性也有所降低，侵蚀坑的大小和严重程度都有所减少。本文对这些基本机制进行了深入探讨。

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
