Notes:
The diesel engine cylinder was processed by laser honing (LH) device, the structuremorphology was observed with scanning electric mirror (SEM), and lubricant consumes and wearperformances were measured, at the same time the mechanism of LH and effects of laser parameterson LH results were analyzed. The experimental results are shown that LH is a kind of phasetransformation treatment by laser, which processes a hardening belt in the certain distributing formon the work-piece surface, and forms the hardness distribution of soft and hard materialalternatively; LH may lower the engine oil consumes 30%-60%, and reduce the pollution of thecatalyst machine, and lower the grain let of the engine oil 25%-30%. LH intentionally machines thegrain cave, which has the certain angle, depth, and width etc.. The surface microcosmic sculptinghas the lubricating function for usage process, and storage and transport lubricant, which improvesthe rubbing condition, then lower the part wear and increase the other performances. Theshort-wave laser is more applicable to the LH process, which improves the lubrication condition,and increases the service life of the engine and the efficiency, and lowers the engine oil consumes
