Abstract: Surface, serving as the fingerprint of a component, is the basis of the following investigations on lubrication, asperity contact, wear and friction, monitoring and controlling, etc. Researchers usually understand a surface from the perspective of a classical single-stratum surface, while ignore the bi-Gaussian stratified characteristic exists in a two-process or worn surface. Some researchers proposed a bi-Gaussian stratified surface theory from the processing and manufacturing of two-process surfaces, and then extended to worn surfaces. In the present study, a review of bi-Gaussian-stratified-surface-theory works is given with respect to surface characterization and simulation, lubrication and contact, wear and friction, and monitoring and controlling, which particularly focuses on the field of mechanical seals. The interesting bi-Gaussian issues those can be further explored are also discussed. It will benefit the design and analysis of mechanical seals.

Key words: acoustic emission, asperity contact, lubrication, mechanical seal, surface topography, wear and friction
