What is the reason do ceramic bearings rust of hybric bearing?

1. Humidity do ceramic bearings rust for hybric bearing: the amount of humidity in the air has a great influence on do ceramic bearings rust for hybric bearing. At critical humidity, the rate of metal rust is very slow. Once the humidity exceeds the critical humidity, the rate of metal rust will suddenly increase. The critical humidity of steel is around 65%. Due to the poor air flow in the bearing production workshop, the heat generated during the processing accelerates the evaporation of moisture from the grinding fluid, cleaning fluid and anti-rust liquid into the air, so that the humidity of the air in the workshop is above 65%, even 80%. It is easy to cause corrosion of bearing parts.

2. Temperature do ceramic bearings rust for hybric bearing: temperature also has a great impact on corrosion. Studies have shown that when the humidity is higher than the critical humidity, the rust rate is increased by about two times for every 10 °C increase in temperature. When the temperature difference changes greatly, the condensation generated on the surface of the do ceramic bearings rust for hybric bearing will greatly accelerate the corrosion. During the processing of the bearing, due to the temperature difference between day and night or the temperature difference of the environment, condensation will occur on the bearing surface, causing corrosion.

3. hand sweat do ceramic bearings rust for hybric bearing: there are corrosive substances such as lactic acid and sodium chloride in the hand sweat. In the process of processing and assembling the hybrid bearing, if the bearing parts are removed by hand, the sweat is not cleaned in time. "Fingerprint rust." Especially in the summer of sweating, this phenomenon is more serious.

4. Oxygen do ceramic bearings rust for hybric bearing: oxygen can be dissolved in water during storage, the concentration of oxygen corrosion can be seen at any time, the solubility of different parts will change. When the bearings are stacked, the oxygen is insufficiently inflated in the middle of the overlapping surface, the water concentration is low, the edge oxygen is sufficient, the water concentration is high, and rust often occurs at the peripheral edge portion of the overlapping surface.

5. pickling, acid printing liquid do ceramic bearings rust for hybric bearing: the pickling method commonly used in bearing processing to show defects such as burns, cracks and decarburization; some large bearings need acid stamping number. After the bearing parts are pickled or acid-printed, if the cleaning is not clean, the neutralization is not complete, and the do ceramic bearings rust for hybric bearing parts will rust. In addition, when the acidic substance comes into contact with the bearing parts, it also causes rust.

6. soot, dust, gas, dust, gas, etc.do ceramic bearings rust for hybric bearing, there are a lot of sulfur dioxide, carbon dioxide and other substances in the soot. These substances will cause corrosion of the parts of the housing, the dust in the air will fall on the product. The state of the bearing surface reduces the critical humidity, and the dust is easy to absorb moisture, which becomes a rusting medium and causes spot rust.

7. ventilating equipment do ceramic bearings rust for hybric bearing: thermal ventilation in summer, the ventilation equipment used in the plant causes a large amount of moisture and corrosive substances in the air to be blown onto the surface of the bearing parts, and the temperature of the product is lowered due to ventilation, resulting in “ Do ceramic bearings rust for hybric bearing

8. Demagnetization is not pure do ceramic bearings rust for hybric bearing: Because the residual magnets of the parts are easy to adsorb iron dust and dust, and are not easy to clean, it is easy to absorb moisture.

9. bump hurt do ceramic bearings rust for hybric bearing: the bearing parts in the grinding process, scratches, mechanical damage such bump hurt other parts of the surface of the lesion and the state of damage do ceramic bearings rust for hybric bearing.

10. residual ceramics do ceramic bearings rust for hybric bearing: if quenched by salt bath, the residual salt on the surface of the workpiece after quenching is not cleaned, so it is easy to absorb moisture.
