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.
Claims20
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.
1 more element
An article of manufacture, comprising
- a substrate of a crystalline material;
- a lubricant;
- a film on the substrate consisting of a tribologically worn structure of at least about 40% by volume of an amorphous structure.
