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 10 - 20 bearing electrochemical corrosion caused by what key elements of the bearing metal corrosion is made up of all sorts of nature and caused by the external factors, in particular the key are: 1) metal composite materials its composition and structure; ( 2) The smoothness of the metal surface ( Etching with oxygen concentration difference charge batteries) ； Contact with the surface of the metal composition and ph value of aqueous solution; (4) working temperature and environmental humidity; 5. Various natural environment material in contact with the metal surface. Why hand sweat will cause rust metal materials? Sweat is a kind of color not completely transparent or light yellow liquid, salty flavour acid, its ph value of 5 - 6. In addition to the sodium, potassium, calcium, magnesium salt, also with a small amount of urea solution, sodium, citric acid, lactic acid bacteria and other organisms. Sweat contact metal materials, can produce sweat film on metal surface produces photoelectric catalysis to metal materials, corrosion of metal materials. People sweat is difficult to avoid, to avoid rust hand sweat to manufacturing workers should carry glue glove, refers to, or use the common tools take put parts, need not specialty touch goods at random.

Non-standard bearing installation, symmetry and auxiliary bearing on the vertical earth pressure in, cannot use the hammer, especially it is strictly prohibited to knock on the bearing immediately. When bearing ring loose, in conjunction with a hole to repair a hole or changing a bearing, don't have to choose to cooperate with each other in the bearing surface as black spots or pad copper make applications. When bearing dismantling to apply suitable pull pull the bearing, cannot use woodworking chisel, a hammer knock bearing, etc.
