Abstract: The surface of friction units is operated with the
processing of laser honing to form linearly extending lubricant channels
and grooves of the predetermined width, depth, angle, shape and gap. The
said channels and grooves can be well-matched to the needs of
lubrication. This technology is considered to specially fit to laser
microcosmic sculpture on the surface cylinder bore. It results in not
only remarkably improving the property of wear-resistance of cylinder
and its life span, but also largely decreasing HC ejection of the
internal combustion engine, its consumption of fuel oil and lubricant,
the pollution of catalytic apparatus and the cost of piston.
