Abstract
We quantitatively measured the mass transfer from friction surfaces, specifically brake pads and rotors, using laser plasma spectroscopy. Specifically, we modelled the mass transfer from the pad to the rotor and measured the elemental diffusion intensity distribution in the rotor material using laser plasma spectroscopy. The main elements measured were Cu, Ni, Ti, and Cr, and the distribution of these after transfer was measured as the ratio of the atomic peak and the ion peak of the plasma in the rotor exposed to friction and the surface composition of the rotor and the roughness, respectively. We measured and quantified the diffusion coefficient for each element through the mass transfer model and found that Cr obtained the largest diffusion coefficient (D) of the elements measured based on this system with a value of $1.9484{\times}10^{-15}m^2/s$.
