Abstract
The influence of temperature on the autophoretic coating's formation from c arboxylated butadiene-styrene copolymer on steel samples was investigated i n the range 0-60 degrees C. Above 20 degrees C, film destruction processes begin to take place. A kinetic equation is proposed to describe both proces ses of formation and destruction of the film. The apparent activation energ y of about 20 kJ mol(-1) for the film growth process is in agreement with t he proposed mechanism for which the rate-determining step is the diffusion of iron ions through the film.
