Adsorbed-gas lubrication systems using hard coatings and ceramics
Adsorbed-gas lubrication using hard coatings opens new possibilities for interfaces in MEMS and precision machinery
Adsorbing nitrogen gas onto carbon nitride coatings produces a friction coefficient of 0.003 without oil lubrication, comparable to oil-lubricated conditions. This approach is promising for micromachines and other compact equipment in which oil and wear particles make conventional solid lubricants difficult to use. Our goals are to clarify the mechanism of low friction produced by adsorbed gas, create carbon nitride coatings for practical applications, and establish tribosystem design guidelines.
