Abstract

The invention discloses a vacuum reaction magnetron sputtering coating device for the inner cavity of an engine cylinder liner, comprising: a vacuum sputtering chamber, a cylinder liner support, a magnetron cathode structure and a motion control mechanism; the cylinder liner support is fixed on the The bottom of the vacuum sputtering chamber; the motion control mechanism is installed on the top of the vacuum sputtering chamber, and connected to the magnetron cathode structure to drive it; The inner surface is coated, so that the inner surface of the cylinder liner has better high temperature resistance and wear resistance; not only can the inner surface of the cylinder liner be fully covered with coating, but also can achieve uniform coating.

Description

technical field [0001] The invention relates to the technical field of vacuum coating, in particular to a vacuum reaction magnetron sputtering coating device and method for the inner cavity of an engine cylinder liner. Background technique [0002] The cylinder liner is one of the key parts of the automobile engine. The inner surface of the cylinder liner is subjected to high temperature and high pressure gas for a long time, and always has high-speed sliding friction with the piston; therefore, its wear resistance and high temperature resistance must be improved; the wear resistance of the inner surface The durability plays a decisive role in the life of the cylinder liner; so far, there are many methods to improve the wear resistance of the cylinder liner, such as surface laser quenching treatment, thermal spraying, etc.; [0003] However, the existing treatment methods have certain limitations. For example, in order to ensure the lubricating effect, the laser quenching tr...
