A Novel Analytical Approach Using TOF-SIMS for Imaging the Distributed States of Constituent Components in Friction Materials

Friction materials are consisted of mixed organic and inorganic raw materials to achieve aimed brake performance and physical properties. In order to manufacture friction materials with stable quality, it is desired that these raw materials are uniformly dispersed, and at the same time it is important to understand the state of distribution during material developments. However, it is difficult for visualizing the dispersion of organic materials, and there are few reports of effective methods. In this study, a use of TOF-SIMS is established as a novel analytical approach for imaging the distributed states of constituent components in friction materials.
