Restorative maintenance and build-up

The article provides the sequence for work performance on selecting a rational method to restore worn-out part surfaces. It contains analytical dependencies to define the factors for wear resistance, fatigue and adhesion resistance as well as a generalized durability factor. The paper demonstrates aggregative values of these factors for various restorative maintenance methods. The author also gives the dependences to define technical and economic criteria of the proposed restorative maintenance methods. More
