| Résumé: | The effects of composition of alloy steel on the friction and wear characteristics of molybdenum dithiocarbamate MoDTC were studied in reciprocated sliding contact using a ball-on-plate type tester. The oil used was squalane of a pure hydrocarbon. The excellent friction and wear characteristics were obtained with high speed steel M50 containing Mo at 4.25 and Cr at 4.12 mass % and bearing steel SUJ2 containing Cr at 0.45 mass %. Especially, M50 with high Mo and Cr content used as the upper ball specimen gave a very low coefficient of friction. A MoO3 surface film formed in advance was confirmed to be effective in improving the friction and wear characteristics of MoDTC. |
