| Abstract: |
| Brush seal system was used on high-pressure compressors and turbine blades in advanced turbo-engines. The solid lubricating and wear-resistant coatings prepared on turbo-engines by thermal spraying technology would not only reduce the wear rates of the rotor shafts and brushes, but also satisfy the harsh service environment need for the brush seal parts. This is an advanced NiCoCrAlY/Al2O3-10%B4C high temperature solid lubrication wear resistant coating used in brush seal parts of turbo-engines. The work aims to improve its oxidation resistance property. |
