Conditions for Transfer Film Formation and Its Effect on Friction Coefficients in NAO Friction Materials Containing Various Abrasive Components
The non-asbestos organic friction materials with various abrasives such as ZrO 2 , ZrSiO 4 , Al 2 O 3 , Fe 3 O 4 were manufactured and underwent friction tests to find conditions for transfer film formation and their effect on friction coefficients, and also the effect of different abrasive componen...

were manufactured and underwent friction tests to find conditions for transfer film formation and their effect on friction coefficients, and also the effect of different abrasive components was analyzed. Friction tests were composed of the effectiveness test and the fade & recovery test successively and counterpart disks were examined at each stage to find transfer film distribution changes. Friction surface observation by SEM revealed that the transfer film was formed not in the effectiveness stage which simulated the normal braking condition, but in the fade stage when temperature rose up to 600°C. The level of friction coefficients for most friction materials turned out to be opposite to the quantity of transfer film formation implying that the transfer film reduced the friction coefficient. High temperature condition was requisite for transfer film generation, but the transfer film was hardly formed irrespective of the magnitude of deceleration rate under moderate operating conditions where temperature stayed below 350°C.
