GLID- ELLER TAETNINGSELEMENTKOMBINATION. |
摘要 |
Combinations of frictional and sealing elements made from hard substances, such as sintered aluminum oxide, are ground and lapped at their surfaces of engagement. At least one surface has at least some micro-blurred areas. The micro-blurring is produced by chemical etching. Phosphoric acid can be used as the chemical etching, and in thermal etching, the etching temperature is between 1400 DEG and 1560 DEG C. |
