The Performance of Machine Parts by the Mechanic Method

Abstract

Machine parts that have passed their duty and have defects on their working surfaces are restored by various methods. When choosing a restoration method, it is necessary to take into account the amount of spread, surface characteristics, and hardness of the detail material, detail dimensions, and wear values. To restore the geometric shape and dimensions of the details, the method of covering a new layer instead of the spread material layer, the method of elastic deformation (changing the shape of the detail due to the redistribution of the existing volume of metal), the method of replacing the spread part of the detail with a new one, mechanical processing of the spread surface, removing the defective layer and giving the detail the correct geometric shape is used.
