Abstract

TiN/TiAlSiN nanocomposite multilayer coatings were deposited on a titanium alloy by multi-arc ion plating. The investigation of the wear behavior of TiN/TiAlSiN multilayer coatings against Si3N4 was conducted at temperatures of 25 °C, 300 °C, and 500 °C using a ball-on-disk tribometer. Additionally, to gain a deeper understanding of medium-temperature oxidation products, an oxidation test was performed at 500 °C for 10 h. The microstructure and chemical composition of the coatings were evaluated by X-ray diffraction and scanning electron microscopy. The primary peak in the XRD pattern of the multilayer coating changed from TiN (111) to Ti3AlN (111) after the oxidation test. The hardness of the TiN/TiAlSiN multilayer coating was 1540 HV0.1, representing a notable five times improvement compared to the substrate. The critical load in the scratch test was 52.3 N, indicating robust adhesion performance. The wear rate exhibited a sharp increase from 25 °C to 300 °C, compared to the rise from 300 °C to 500 °C. Furthermore, the friction coefficient of the coated sample was more stable than the substrate, with different scratch track morphologies between the samples before and after the oxidation test.
TiN/TiAlSiN 纳米复合多层涂层从常温到中温的磨损行为
通过多弧离子镀在钛合金上沉积了 TiN/TiAlSiN 纳米复合多层涂层。在 25 ℃、300 ℃ 和 500 ℃ 温度条件下,使用球盘摩擦磨损试验仪研究了 TiN/TiAlSiN 多层涂层对 Si3N4 的磨损行为。此外,为了更深入地了解中温氧化产物,还在 500 °C 下进行了 10 小时的氧化试验。氧化试验后,多层涂层 XRD 图谱中的主峰从 TiN (111) 变为 Ti3AlN (111)。TiN/TiAlSiN 多层涂层的硬度为 1540 HV0.1,与基底相比显著提高了五倍。划痕测试的临界载荷为 52.3 N,表明涂层具有良好的附着性能。从 25 °C 到 300 °C 的磨损率急剧上升,而从 300 °C 到 500 °C 的磨损率则有所上升。此外,涂层样品的摩擦系数比基底更稳定,氧化测试前后样品的划痕轨迹形态各异。

期刊介绍: Coatings is an international, peer-reviewed open access journal of coatings and surface engineering. It publishes reviews, research articles, communications and technical notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. Full experimental and/or methodical details must be provided. There are, in addition, unique features of this journal: * manuscripts regarding research proposals and research ideas will be particularly welcomed * electronic files or software regarding the full details of the calculation and experimental procedure - if unable to be published in a normal way - can be deposited as supplementary material
