Research of the alloy VZh 98 with the system Co-Mo-Cr-Si-B interaction processes

The purpose of the work is the research of the processes of the interaction of the system Co-Mo-Cr-Si-B with the heat-resistant nickel alloy VZh 98 concerning the development of the technology of strengthening of the contact surfaces of the working blades of the ship gas turbine engines. During this work the methods of the microroentgen spectral analysis, the electron microscopy were used. The adhesive activity of the researched alloys was researched by the method of horizontal drop. It showed that the experimental compositions have high adhesive activity relating to the heat-resistant nickel alloys at the temperatures 1190...1210 ℃, which creates the favourable conditions for their use in the ship gas--turbine building.
