| 摘 要： | 介绍了陶瓷挺柱和金属凸与对试验研究的结果，研究表明，陶瓷挺柱的粗糙度是影响金属员的主要因素。上海内燃机研究所研制的氮化硅－－金属复合挺柱和球墨铸铁表面淬火凸轮，经过２０００ｈ发动机台架试验，陶瓷挺柱的磨损是原机挺柱磨损折１／６，球铁表面淬火凸轮的磨损是原机凸磨损的１／５。

| Abstract: | An investigation of matching the ceramic tappet with the metallic cams is presented in this paper. The results show that the main factor which influences the cam wear is the roughness of the ceramic tappet. A ceramic-metal compound tappet (its working surface is inlaid with a sheet of silicon nitride),and a spheroidal graphite cast iron cam with induction hardening have been developed by SICERI. The 2000h engine bench test results show that the wear values of the ceramic tappet and the spheroidal graphite cast iron cam with induction hardening reduce by a factor of 6 and 5 respectively, compared with those of conventional parts under similar engine operating conditions. |
