| Abstract |
Wear resistance properties of pearlite cast iron have been studied when nitrided at 650℃ with C-H-N-O type nitrogen gas forming agent. The results found are W_c (㎎/㎠)=0.675×[applied load (㎏/㎠)] for non-nitrided cast iron W_c (㎎/㎠)=0.225×[applied load (㎏/㎠)] for nitrified specimen. Where W_c is wear loss per unit area, under the conditions of applied load if 4㎏/㎠, speed 1 m/sec and distance 400㎞-1,400㎞. And also it is found that the sear rate are 6.0 ㎍/㎠·㎏ and 0.67㎍/㎠·㎞ for non-nitrided and nitrided specimens respectively. |
