description: The aim of the work is to analyze the possibility of restoring machine parts by pressing a powder layer onto the inner surface. Work tasks: 1. Classification of methods for restoring machine parts. 2. Analysis of the possibility of restoring machine parts by powder methods. 3. Study of the properties of the initial powder materials. 4. Implementation of experiments on pressing a powder layer onto the inner surface of a part of the âsleeveâ type. 5. Evaluation of the Technological properties of the resulting workpiece. It is shown that one of the promising methods is to press the powder onto the inner surface of parts of the "sleeve" type, this method provides the possibility of varying the chemical, granulometric composition and technological properties of powder materials, which makes it possible to obtain higher functional properties compared to the original parts and can also be provided higher economic performance.
