The paper discusses
environmental issues of coating stripping processes based on chemical and
plasma electrolytic techniques. An approach based on ISO 14000 standard was proposed for evaluation of the environmental efficciency of the coating stripping processes. It was
shown the that plasma electrolytic technique is 25%
more environmentally efficient than the chemical technique of the defective
coating removal. It has been shown that the application of the plasma
electrolytic technique is the most effective for stripping of multiphase
coatings, while for simple coatings the efficiency of the both methods is
similar.
Key words: protective
coating, coating removal, plasma electrolytic technique, chemical technique,
