| Abstract: |
| The paper discusses the attempts to apply modern welding methods in regeneration of machine parts and devices, including such as: plasma hard facing and spraying, as well as electrical surfacing and brush-plating methods. The elements of a technologicaI process of repair are discussed: preparation of the parts for regeneration, automatization and robotics of the process. Special impoftance should be attached to the qualities of the layers.ln this paPer, the experimental results of plasma hardfacing composite layers are presented.Corrosion and wear resistance, as well as costs are the main elements considered in comparison and application of various modern regeneration technologies. |
