摘　　要：本文研究不同类型石墨的灰口铸铁的铸态与离子渗氮试样,以不同冲击速度下在海水与砂粒混合的介质中的腐蚀磨损的表面特征。试验表明:铸铁铸态试样的表面呈橙黄色,有高低不平的沟槽,冲击速度愈大,石墨片愈粗,沟槽明显;离子渗氮处理的铸铁试样的表现呈灰色,表面高低不平不明显,在试验时间内与冲击速度和石墨大小不明显。It has been studied that grey cast iron which is in as - cast condition or is treated in plasma nitriding, exhibits the surface feature of corrosion wear in sea - water mixed with fine sand at the different impact speed. The results show: the as - cast iron sample surface incurs organge colour and plow grooves; with increasing the impact speed and coarsening the graphite flake, the plow grooves are obvious, the sample surface treated in plasma nitriding incurs grey colour and slight plow grooves; increasing the impact speed and coarsening the graphite flake are little influence upon the plow groove.
