技术领域
本发明涉及润滑涂料领域,具体涉及一种润滑涂料、润滑涂层及其制备方法和应用。
背景技术
我国空间站建造过程中设计采用了大型齿圈与齿轮摩擦副,由于齿圈尺寸较大,难以通过热烘烤在其表面固化制备粘结固体润滑涂层,并且由于该零件处于空间低轨环境中服役,存在原子氧侵蚀,且运转寿命较长,急需一种具有良好耐原子氧性能与耐磨损性能的常温固化润滑涂层。
霍丽霞等(表面技术,2014(43),111-115)开展了基底材质对硅酸纳粘结MoS2固体润滑涂层摩擦学性能的影响,但这类硅酸纳粘结MoS2固体润滑涂层为单组份高温固化型涂层,且所采用的MoS2固体润滑剂未经超支化聚硅氧烷表面修饰,难以用于大型齿圈表面。
发明内容
因此,本发明要解决的技术问题在于克服现有技术中二硫化钼基固体润滑涂层耐原子氧性能不足以及大型机械活动件难以热烘烤固化的的缺陷,从而提供一种润滑涂料、润滑涂层及其制备方法和应用。
