Title:
DEVICE FOR AND METHOD OF PRODUCING FINE IRREGULARITY
Document Type and Number:
Japanese Patent JPS5262797
Kind Code:
A
Abstract:
A method and apparatus for producing microasperities for enhancing lubrication is provided. A pulsed laser beam or other heat source having high resolution with respect to time and space is focused onto a surface such as a thrust bearing surface to produce an array of microasperities of controlled size, shape and density. The staggered ramp shaped asperities produce an enhanced lubrication effect.
