摘要

本研究对aisi316l不锈钢进行了等离子氮化和DLC涂层的磨损性能研究。将氮化样品与双相（PN + Cr/WC/DLC）样品进行比较。采用PECVD-MS法制备了Cr/WC/DLC膜。结果表明，低温等离子体渗氮在软质316L基体上形成的无氮化层具有较高的硬度。此外，它为Cr/WC/DLC薄膜的沉积提供了优异的承载能力，降低了复合涂层的硬度梯度。PN + Cr/WC/DLC涂层的磨损率比PN层低一个数量级，表现出优异的磨损性能。316L的磨损机制以黏着磨损为主，PN层主要发生磨粒磨损和氧化磨损。相比之下，PN + Cr/WC/DLC涂层显示出几乎难以察觉的磨损痕迹，表明具有优异的耐磨性。

Wear performance of plasma nitrided and DLC coated AISI 316L stainless steel

In this study, the wear performance of plasma nitrided and DLC coated AISI 316L stainless steel were studied. Nitrided samples were compared with the duplex ones (PN + Cr/WC/DLC). The Cr/WC/DLC films were deposited by a PECVD-MS process. As a result, it was concluded that the nitride-free nitrided layer formed on the soft 316L substrate through low-temperature plasma nitriding exhibits high hardness. Additionally, it provides excellent load-bearing capacity for the deposition of the Cr/WC/DLC film, reducing the hardness gradient of the composite coating. The wear rate of PN + Cr/WC/DLC coatings is an order of magnitude lower than that of the PN layer, demonstrating superior wear performance. The wear mechanism of 316L is predominantly adhesive wear, while the PN layer mainly undergoes abrasive and oxidative wear. In contrast, the PN + Cr/WC/DLC coating displays nearly imperceptible wear tracks, indicating superior wear resistance.

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.
