CN107740054A 一种CrAlTiN涂层及其制备方法 有权

一种CrAlTiN涂层及其制备方法
Abstract:
本发明公开了一种CrAlTiN涂层结构，其包括基体、AlCrTi合金过渡层和CrAlTiN涂层，AlCrTi合金过渡层与基体结合，CrAlTiN涂层与AlCrTi合金过渡层结合，所述CrAlTiN涂层是由AlN、CrN、Ti9Al23、Al2Ti等纳米晶相构成的纳米晶复合结构涂层。这种含有多种纳米晶相的纳米晶复合结构保证了涂层的高硬度、耐磨性热稳定性和化学稳定性。CrAlTiN涂层厚度均匀且结构致密，与基体具有良好的结合强度。CrAlTiN涂层制备工艺重复性好，与多层膜相比，前者应用范围更广，实用性更强，尤其应用于复杂的零部件表面，具有独特优势。
Abstract(English):

The invention discloses a CrAlTiN coating structure which comprises a base body, an AlCrTi alloy transition layer and a CrAlTiN coating. The AlCrTi alloy transition layer and the base body are combined, and the CrAlTiN coating and the AlCrTi alloy transition layer are combined. The CrAlTiN coating is a nanocrystal composite structure coating composed of AlN, CrN, Ti9Al23, Al2Ti and other nanocrystals. By means of the nanocrystal composite structure containing the multiple nanocrystals, high hardness, wear resistance, heat stability and chemical stability of the coating are ensured. The CrAlTiNcoating is uniform in thickness and compact in structure, and good combining strength is achieved on the CrAlTiN coating and the base body. Repeatability of the preparing technology of the CrAlTiN coating is good, the application range of the CrAlTiN coating is wider compared with a multilayer film, practicability is higher, and the CrAlTiN coating especially has unique advantages when applied tocomplex part surfaces.
