Abstract

The invention discloses a non-oil-stick triple-combination piston oil ring and a fabrication method thereof. The surfaces of a bushing ring and a scraper are subjected to ultrasonic cleaning and then phosphating; a thin phosphate layer is formed on the surface of a ring body; then, a non-oil-stick coating is sprayed; and a dense non-oil-stick coating is formed on the surface of the bushing ring and the scraper by drying and solidifying. The non-oil-stick coating consists of molybdenum disulfide and polytetrafluoroethylene; after the non-oil-stick coating is sprayed on the surface or the surfaces of the bushing ring or the bushing ring and the scraper, the liquidity of lubricating oil on the surface of the ring body is improved, the problem that carbon is easily formed on the surface of the existing triple-combination oil ring to result in high oil consumption is solved, the oil consumption is lowered, and an engine can be energy-saving and environment-friendly truly.

Description

1. Technical field: [0001] The invention relates to a three-combination steel belt piston oil ring and a preparation method thereof, in particular to a three-combination oil ring whose surface is sprayed with a non-stick oil coating and a preparation method thereof. 2. Background technology: [0002] With people's increasing awareness of protecting the environment and reducing pollution, the requirements for low fuel consumption and low emissions of vehicles are becoming more and more stringent. Therefore, how to further control the consumption of engine lubricating oil and reduce and purify exhaust emissions is an urgent requirement for the current development of automobiles. Piston ring is the core component of the engine, and oil control is one of its important functions. When the piston ring is working, it moves upwards to spread oil on the inner wall of the cylinder liner to promote lubrication and reduce the friction and wear of the ring and the cylinder liner. Movin...
