Abstract
An article of method of manufacture of a low friction tribological film on a substrate. The article includes a substrate of a steel or ceramic which has been tribologically processed with a lubricant containing selected additives and the additives, temperature, load and time of processing can be selectively controlled to bias formation of a film on the substrate where the film is an amorphous structure exhibiting highly advantageous low friction properties.
Claims16
A method of forming a low friction tribological surface film comprising:
- providing a substrate having a crystalline structure and an opposing wear member;
- providing a lubricant;
- and
- controlling operating conditions during tribological rubbing processing, to form a film on the substrate wherein the film comprises an amorphous structure formed by the tribological rubbing processing.
A method of forming a low friction tribological surface film comprising:
- providing a substrate having a crystalline structure and an opposing wear member;
- providing a lubricant;
- and
- controlling operating conditions during tribological rubbing processing, such that λ ratio is less than 0.2, to form a film on the substrate wherein the film comprises an amorphous structure formed by the tribological rubbing processing, the film having at least 30% amorphous phase.
