滚动轴承锈蚀机理分析

重点探讨了金属在大气环境的电化学腐蚀机理,分析了影响轴承锈蚀的主要因素,提出了轴承防锈的基本思路和方法。大气环境中轴承的锈蚀主要是由电化学腐蚀产生,偶然伴随化学腐蚀反应。提高轴承材料的防腐性能,利用可靠的防锈材料在轴承表面形成完整致密的保护膜,严格控制工作环境的温湿度及其变化,可以有效保证轴承在生产和使用中不发生锈蚀。

Analysis on Corrosion Mechanism of Rolling Bearings

The electrochemical corrosion mechanism of metal in the atmospheric environment is mainly discussed,the main factors influencing bearing corrosion are analyzed,and the basic idea and rust-resistance method are put forward for bearing.The bearing corrosion in the atmospheric environment is mainly induced by electrochemical corrosion,accidentally followed along with chemical corrosion.The corrosion prevention in the bearing production and use is guaranteed by improving the anti-corrosion property of bearing material,using reliable rust-resisting material which can form a complete and compact protective film in the bearing surface,strictly controlling the temperature and humidity of the work environment and their variations.
