| Turbine blades of aircraft gas-turbine engines were always the place to apply novel materials and technologies. Special attention was paid to strength, cor- rosion-oxidation, and tribological performance. The blade top-shrouds are one of the most vulnerable places from the point of wear resistance. This problem was usually solved by applying coatings (weld-deposition, electro- spark coating, gas-spray coatings). The new method proposed here is to use soldering technology: the to-size plate manufactured of wear-resistant ma- terial is bonded to the friction surface by the solder with the composition close to the composition of the turbine blade. In this work, we propose the method and the material for improving the wear resistance of the turbine blade’s top shrouds. The cobalt-based materials (Co-15Cr-2.5Fe-2.5Al-36TiC) seem very promising for this. In the present work, the manufacturing tech- nology of the alloy by HIP method, microstructure, and high-temperature fretting-wear characteristics (1050 ̊C) are discussed. |
