Abstract

Co-MoS2 composite coatings were deposited by the magnetic jet electrodeposition under different magnetic field intensities. The growth orientation and deposition mechanism of Co-MoS2 composite coatings under magnetic jet electrodeposition were analyzed based on the weak adsorption theory of nanocomposite co-deposition. Research showed that the coating topography changed from a blade-like structure to a cellular structure, and the cellular structure became a granular protrusion structure with increase of the magnetic field intensity. Compared with Co-MoS2 composite coating in jet electrodeposition, the orientation of Co shifted from (110) to (101) as the magnetic field intensity increased in magnetic jet electrodeposition. The adhesion, microhardness, adhesion, corrosion and wear resistance of the composite coatings were enhanced, which was attributed to the influence of the magnetic field on the growth orientation of the composite coating and the coordinated lubrication effect in the Co-MoS2 composite coating.

不同磁场强度下通过磁喷射电沉积沉积钴-硫化钼复合涂层的研究

在不同磁场强度下，采用磁喷射电沉积法沉积了 Co-MoS2 复合涂层。基于纳米复合材料共沉积的弱吸附理论，分析了磁喷射电沉积下 Co-MoS2 复合涂层的生长取向和沉积机理。研究表明，随着磁场强度的增加，涂层形貌由叶片状结构转变为蜂窝状结构，且蜂窝状结构转变为颗粒状突起结构。与喷射电沉积中的 Co-MoS2 复合涂层相比，磁性喷射电沉积中随着磁场强度的增加，Co 的取向由（110）转变为（101）。复合涂层的附着力、微硬度、附着力、耐腐蚀性和耐磨性都得到了增强，这归因于磁场对复合涂层生长取向的影响以及 Co-MoS2 复合涂层中的协调润滑效应。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
