为了提高工程材料表面的耐磨性、耐腐蚀性和硬度等机械性能，人们将薄膜和涂层应用于工程材料。本文研究了用物理气相沉积法(PVD)沉积的涂层。涂层的生产是当今与现代表面工程相联系的重要方向之一，以确保获得具有机械特性和耐磨性等高可用性能的涂层。本工作的总体目的是以电子显微镜为主要研究工具，对在镁合金表面获得的Ti/(Ti，Si)N/(Ti，Si)N涂层进行考察和评价。利用扫描电子显微镜和透射电子显微镜对其微观结构进行了测定，并进行了能谱分析和电子衍射分析。在研究涂层材料的同时，研究了涂层和基材之间的过渡区以及沉积过程中可能出现的一些结构缺陷的发生，这些缺陷可能会对所获得的涂层的性能产生任何影响。并对纳米结构涂层的结构特征进行了研究，为解决这一问题提供了可能。在本工作中，本工作的目标是通过物理气相沉积(PVD)技术制备纳米复合薄膜和涂层的研究现状和发展趋势。这项研究将涉及此类涂层的某些方面，但主要目的是概述电子显微镜在PVD涂层研究中的应用所揭示的特征。
Thin films and coatings are applied to engineering materials in order to improve the mechanical properties of the surface, such as wear resistance, corrosion resistance and hardness. This research work deals with coatings deposited by appliance of the Physical Vapour Deposition method (PVD). The presented instigations concerning the production of coatings are one of the present important directions connected with modern surface engineering, ensuring the obtainment of coatings of high usable properties like mechanical characteristics and wear resistance. The general purpose of this work is investigation and evaluation of the obtained Ti/(Ti,Si)N/(Ti,Si)N coatings on magnesium cast alloys using electron microscope as the main investigation tool. The investigations were performed using scanning and transmission electron microscopy for the microstructure determination, also EDS microanalysis and electron diffraction was possible to obtain. While investigating the coating material, there were studied the transition zone between the coating and the substrate material as well the occurrence of some structure defects which can be present after the deposition process and could have any influence of the properties of the achieved coating. Also the structure character will be investigated for the occurrence of the nanostructure coatings, which could be seen as the solution of this issue. In the present work, the goal is set on current practices and future trends for nanocomposite thin films and coatings deposited by physical vapour deposition (PVD) technique. This investigation will touch some aspects of such coatings, but the main objective is to give a general view on features revealed using electron microscopy application in PVD coating investigations.
