摘要：

There is the influence of high temperatures and internal stresses, defects accumulate, which lead to the formation of microcracks of various types, wear and subsequent destruction of the blade during their exploitation. In view of the complexity in the manufacture and high cost of new blades, after the development of their resource, the blades should be restored. This paper shows applying investigation which was directed to make a technological recommendations for restoration cladding of turbine blades. The influence of initial material characteristics and main technological parameters of cladding process on formation of geometry, structure and potential defects of deposited metal is considered. Based on obtained dependencies, criteria that allow producing a defect-free clad with controlled structure and a minimized allowance for further machining are determined. As result of investigation, laser powder cladding technology for restoration of heat-resistant nickel alloys turbine blades is developed.
