Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 Reasoning are given as to perspective abrasive resistant materials selection for local reinforcement of the blades surfaces (such as Z-notch and etc.). In the form of castings and powder composite, obtained by mechanical alloying, experimental materials have been produced on the basis of nickel superalloys JS 32 and IN 738 with titanium carbide TiC phase adding in 30 vol. % (19 wt. %). Via electro spark deposition, microplasma deposition and reaction-assisted diffusion welding methods the technologies for the materials deposition on the contact surfaces of blades have been probed. Metallographic research of deposits specimens of the experimental abrasive resistant materials shows the even distribution of reinforcing titanium carbide phase and its size in the range of 5-30 ?m. Mechanical properties tests are expected to point out an increase in abrasive resistance of perspective materials 1.5-2 times as much as with the common technologies and materials Product Description popup.authors Нікіфоров Денис Леонідович Савченко Віктор Степанович Яровицин Олександр Валентинович popup.nrat_date 2020-04-02 Close
