摘要
通过对国产气门导管与进口气门导管的理化研究,针对其化学成分、宏观形态、金相组织中的石墨形态及磷共晶等方面进行对比分析,明确了影响气门导管加工性能的因素,提出了改善其加工性能的方法,为改善气门导管加工性能提供思路。
Graphite morphology, mierostructure of phosphorus chemical composition, macro morphology and phosphorus eutectic etc were compared through the study of physicochemical for domestic and imported valve shaft guide. The factors affecting the machining performance of valve shaft guide were put forward to improve processing performance. It will provide ideas for improving processing per- formance of valve shaft guide.
