Abstract
The invention discloses a metal composite ceramic cylinder sleeve. Composite film ceramic is attached to the inner surface of the cylinder sleeve, and new material is formed on the metal surface through interdiffusion between the film ceramic and a cylinder sleeve base body material. A ceramic film is BN-SiN, the molecular structure of the ceramic film is of a hexagonal crystal structure and has self-lubrication performance, after ceramic infiltration, the friction coefficient of the inner surface of the cylinder sleeve is reduced to one sixth, and the hardness is improved by 41%. The thickness of the ceramic film layer is 3 micrometers -6 micrometers, and the infiltration depth is 35 micrometers-55 micrometers; and the ceramic composite film grows in the environment at the low temperature of 255 DEG C-265 DEG C. The composite film structure of the metal composite ceramic cylinder sleeve is firm and can not fall off, the inner surface of the cylinder sleeve is resistant to abrasion and high temperature and small in friction coefficient, so that engine power is improved, oil consumption is reduced, and emission pollution is reduced.
