ABSTRACT:
The present invention relates to a process and apparatus that allows a comprehensive evaluation of tribological materials. Such materials include lubricants (liquid, solid and gaseous materials) and load bearing surfaces (bulk materials, surface treatments and coatings). The process and apparatus enable a meaningful characterization of these materials in a way that connects basic lubrication, wear and failure mechanisms with machine hardware in its operational setting.
