Abstract:A model of the codeposition process of particles and metal matrix was proposed in which the process was divided into three steps, that was, particles dispersing uniformly in the plating-liquid, particles transferring to the surface of electrode and being strapped on the surface of electrode. The thermodynamic criteria, the dynamic factors, the physical models and the mathematical models of these three steps were presented. The mathematical model for the whole process was also discussed.

Key words: composite eletrodeposition　mathematical model of codeposition process
