AN X-RAY STUDY OF THERMODIFFUSION PROCESSES ON TYRE WIRE COATING

摘要

The thermodiffusion behaviors of brass coating on tyre wire obtained by electro-deposition 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 phase during different thermodiffusion processes was given and the phase homogeneity of a phase in the films was discussed.
