After the product is put into use, there will be some failures. This has something to do with the type and quality of the product, but it is not always caused by quality problems, and may be caused by improper operation or different operation methods. Some problems in the use of powder metallurgy bearings are summarized in this paper.
 
The most common problem in powder metallurgy bearings is tile corrosion. Through spectral analysis, it can be found that the concentration of non-ferrous metals is higher, and there are more non-ferrous metal costs in the element spectrum, or the corrosion problem is caused by excessive moisture or acid value in lubricant.
 
The diameter surface of powder metallurgy bearings can also be pulled up and corroded to a certain extent, which is also due to the existence of all cutting abrasive grains inside the bearing, the composition of which is mainly non-ferrous metals. If there is some micro wear on the tile back, it may be that the iron concentration is abnormal, and there are more iron components in the sub-micron wear particles.
 
Through analysis and summary, we can obtain the fault cause according to the status of the problems of powder metallurgy bearing, and make effective correction plan to guarantee the effective service life of the product.
