The objective of this work is the development of advanced polymer coatings by electropolymerization and**electrophoretic deposition methods for corrosion protection of injection molds. This project will be focused on**active collaboration of Husky Injection Molding Systems Ltd. and McMaster University. Husky is working on**the development of advanced injection molding equipment with improved corrosion protection. Husky is**interested in the solving of a problem of pitting corrosion of stainless steel injection molds, causing corrosion**induced fractures. This problem results in extensive damage and expensive machine downtime. McMaster**University offers a promising approach to address this problem, which is based on the use of advanced polymer**coating technologies for protection of stainless steel. The research will be focused on the application of**electropolymerization and electrophoretic deposition methods for the fabrication of polymer coatings on**stainless steel injection molds. McMaster University has developed advanced dopants and charge transfer**mediators for the electrodeposition of polypyrrole coatings on non-noble substrates by anodic**electropolymerization. The use of advanced dopants and charge transfer mediators allows**electropolymerization at reduced anodic potential and formation of adherent coatings. Another approach will**be based on the cataphoretic deposition of polyetheretherketone on stainless steel. It is based on the use of**advanced charging and dispersing agents, developed at McMaster University. Corrosion testing of stainless**steel samples and full scale mold parts will provide an insight into the influence of polymers, deposition**methods, deposition parameters, bath formulations and coating microstructures on coating adhesion and**corrosion protection. The development of advanced coatings meets the interests of Canadian industry in**advanced molding equipment, film deposition technologies and corrosion protection. The benefits of this**project will include the generation of new technological solutions, technology transfer to Husky and HQP**training. The resolution of the problem will result in job growth at Husky and increased revenue.
