| Abstract: |
| The tribological properties of a turbojet engine seals were tested using different additives and surface modification . The results showe that two kinds of additives , FORMULA 4 10 and PC 7000 ,and two kinds of surface modification, which include bonderite process and brush plating indium copper alloy, could improve the tribological properties of the tested engine seals. |
