摘要
为提高新型汽车发动机排气门座的耐磨性,第一汽车制造厂研制了铌铬钼钒铸铁排气门座。经1000h 台架强化试验和25000km 道路试验表明,用这种材料制造的排气门座性能良好。
To enhance the anti-wearing ability of exhaust valve seat for a new engine,a Nb-Cr-Mo-V cast iron value seat has been developed in the First Automobile Works.Through a 1000 hours intensive indoor test and a 25 000 km road test,it is shown that a good anti-wearing ability is obtained by using this material.
