摘要

本研究调查了在铍铜上沉积的 Cr/CrN+CrCN/Cr-C:H、Cr/W-C:H 和 Cr/CrN+Ag/Cr-C:H 涂层的使用情况。这些保护涂层是采用磁控溅射物理气相沉积(MSPVD)方法制备的。测试的目的是鉴定外层 DLC(类金刚石碳)层是否具有保护功能和调节热光学特性的作用。这项研究的目的是比较铬基涂层和氮化铬基涂层的性能。使用扫描电子显微镜(SEM)、光电二极管背散射电子(PDBS)和 X 射线色散光谱(EDX)研究了涂层的微观结构、构造和化学成分。使用划痕测试和剥离拉拔法对附着力进行了评估。还测试了对冷焊接效应的保护水平。还进行了热光学、微硬度和表面电阻率测试。结果表明,在需要增强抗冷焊性能的情况下,DLC2 和 DLC3 被证明是最佳解决方案。这种应用的一个例子是管状吊杆天线,这种天线在部署到太空之前都是卷起来存放的。由于火箭发射过程中的振动以及随后暴露在高真空环境中,它们很容易受到冷焊的影响。

Protective Magnetron Sputtering Physical Vapor Deposition Coatings for Space Application
In this study, the use of Cr/CrN+CrCN/Cr-C:H, Cr/W-C:H, and Cr/CrN+Ag/Cr-C:H coatings deposited on copper beryllium were investigated. These protective coatings were prepared using the Magnetron Sputtering Physical Vapor Deposition (MSPVD) method. The tests were carried out in order to qualify the outer DLC (Diamond-Like Carbon) layers for use as the protective function and for regulating the thermo-optical properties. The objective of this study was to compare the properties of chromium and chromium nitride-based coatings. The microstructure, architecture, and chemical composition were studied using scanning electron microscopy (SEM), Photo Diode BackScattered Electrons (PDBS), and X-ray dispersion spectroscopy (EDX). The adhesion was evaluated using a scratch test and a peel and pull-off method. The level of protection against the cold welding effect was tested. Thermo-optical, microhardness, and surface electric resistivity tests were performed. It was found that in cases where increased resistance to cold welding is required, DLC2 and DLC3 proved to be the best solutions. An example of such an application is tubular boom antennas, which are stored in a rolled-up form until deployed in space. They are susceptible to cold welding due to vibration during rocket launch and subsequent exposure to high vacuum.

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
