What are the main factors influencing the bearing metal corrosion

What are the main factors influencing the bearing metal corrosion sources: bearing | last updated: - 2020 07 - And what are the major factors that affect the bearing metal corrosion bearing metal corrosion is caused by a variety of internal and external factors, sum up the main are: (1) chemical composition and structure of the metal material itself; (2) metal surface finish, The oxygen concentration cell corrosion) ; (3) contact with the metal surface composition and pH value of solution; (4) environmental temperature and humidity; (5) the various environmental medium metal surfaces in contact with. Why hand sweat will cause metal corrosion? Sweat is a colorless transparent or light yellow with salty in weak acid liquid, its pH value of 5 ~ 6. In addition to containing sodium, potassium, calcium, magnesium salt, also contains a small amount of urea, lactic acid, citric acid and other organic acids. When contact with sweat and metal on metal surface to form a film of sweat, sweat film will cause electrochemical action on metals, the corrosion of metal. Sweating is inevitable, to prevent hand sweat cause corrosion, production personnel should wear gloves, gloves, or take the parts with specialized tools, don't touch products by hand.
