To clarify the scoring resistance of SCM415H gears with plasma carburizing (gear pair PC) and SACM645 gears with plasma nitriding (gear pair PN) and radical nitriding (gear pair RN), a gear test was carried out using a power-circulating gear machine under forced lubrication. From the test, the following results were obtained. (1) In the case of SCM415H gears, the scoring resistance for the gear pair PC was 785N/mm and it was 2.2 times as large as that for the gears with gas carburizing (gear pair GO. (2) In the case of SACM645 gears, the scoring resistance for the gear pair PN was 721N/mm and that for the gear pair RN was 657N/mm. (3) When the normal load per unit face width was higher than 300N/mm, the value of the sound pressure level of the gears had the following order: gear pair PN>gear pair GC>gear pair RN>gear pair PC. (4) The values of the critical surface temperature for scoring of the gears for the gear pair PC, gear pair PN and gear pair RN were about 130℃〜150℃ higher than that for the gear pair GC.
