摘要
对摩擦副工作表面进行激光珩磨,形成与其表面润滑减摩性能优化匹配的、连续均匀的,并具有一定密度、深度、角度、形状的油路和凹腔。该技术特别适用于对气缸孔表面进行激光微观造型,不仅可以显著提高气缸孔耐磨性能,延长其寿命,而且还大幅度降低内燃机的颗粒排放量、机油耗、燃油耗、催化器污染和活塞环组成本。
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.
