Abstract:

Generally, the service life of aero-bearing is short generally. Through a number of statistical data analysis and further research to the failure gearing, the main problem in the usage of aero-bearing was corrosion and wear. Through various test, it indicated clearly the ion implantation into the test material of aero-bearing and the non-crystal materials appeared on the surface of test material. The feature of anti-corrosion and the feature of anti-wear were 2 times than that before. Meanwhile, Developed ionic beam machine with multiple functions for the ion implantation into the material of aero- bearing solved the problem of non-uniformity implantation on spherical surface. Aero-bearing with ion implantation has been applied in the aero-engine field widely. It not only smoothly succeeded in the engine test on a test bed and gas turbine test on the ground but also all of aero-bearing delivered to China Air force being has a remarkable improvement in the work up to now.

Key words: injection, bearing, corrosion, wear
