摘要

采用物理气相沉积(PVD)工艺，在接收到的AZ91D镁合金表面涂覆ZrO2和ZrN陶瓷。在滑动速度为2 ~ 8 m/s、正常载荷为2 ~ 10 n的销盘式磨损试验机上进行了干滑动磨损试验，观察了磨粒、脱层、热软化和氧化等磨损机制。结果表明，PVD涂层提高了AZ91D镁合金的耐磨性。利用扫描电子显微镜(SEM)对磨损表面进行了观察。

Study on wear behaviour characteristics of ZrO2 and ZrN coated AZ91D Mg alloy

The as received AZ91D Mg alloy was coated by ZrO2 and ZrN ceramic using Physical Vapour Deposition (PVD) process. The dry sliding wear studies were carried out in a pin-on-disc wear tester at a sliding speed of 2-8 m/s and in normal loads of 2- 10 N. The wear mechanism such as abrasive, delamination, thermal softening and oxidation were observed. The results showed that the PVD coating increased the wear resistance of the AZ91D Mg alloy. The worn out surface were examined by using Scanning Electron Microscope (SEM).

期刊介绍： University of Belgrade, Technical Faculty in Bor, has been publishing the journal called Journal of Mining and Metallurgy since 1965 and in 1997 it was divided in two independent journals dealing with mining and metallurgy separately. Since 2009 Journal of Mining and Metallurgy, Section B: Metallurgy has been accepted in Science Citation Index Expanded. Journal of Mining and Metallurgy, Section B: Metallurgy presents an international medium for the publication of contributions on original research which reflect the new progresses in theory and practice of metallurgy. The Journal covers the latest research in all aspects of metallurgy including hydrometallurgy, pyrometallurgy, electrometallurgy, transport phenomena, process control, solidification, mechanical working, solid state reactions, materials processing, surface treatment and relationships among processing, structure, and properties of materials.
