AN X-RAY STUDY OF THERMODIFFUSION PROCESSES ON TYRE WIRE COATING
(Department of Materials Science and Engineering，Northeastern University，Shenyang 110006)
Abstract: The thermodiffusion behaviors of brass coating on tyre wire obtained by electro-deposi tion of copper-and zinc with controlled thickness，followed by continuous annealing in industry and isothermal annealing at laboratory，respectively, were studied by means of X-ray diffraction analysis.With the information of X-ray diffraction，the fraction of β phase during different thermodiffusion processes was given and the phase homogeneity of α phase in the films was discussed.
