Abstract
A system and method for reducing interaction between surfaces (10,12) moving relative to each other. The system includes a first surface (10) having a first number of repetitive surface asperities (14), e.g., 11, per unit length of surface, and a second surface (12) having a second number of repetitive surface asperities (16), e.g., 13, per unit length of surface, with the first and second numbers being in relative prime ratio, i.e., having no common divisor other than 1. The ratio of repetitive surface asperities may be controlled as a function of component particle size, grain size; groove size; or relative angular orientation of the surfaces (110,112).
