Development of reinforced aluminide matrix for wear-resistance coatings using HVOF deposition

This project aims at developing new coating materials exhibiting high oxidation, corrosion and wear resistance to addresses the specific needs of power generation equipment, which operate under severe erosion and abrasion conditions in corrosive environments. A possible solution is proposed by providing a coating based on a modified iron aluminide matrix in which boride hard particles are formed in-situ in order to enhance its wear resistance. Such a coating is designed and engineered either for application on new parts or to refurbish worn parts. The coating formulation is chosen and optimized to fulfil the mechanical and the chemical requirements while the application methods are chosen and optimized to achieve the maximum material performance taking into account the technical and economic considerations. In addition to the direct benefits to our industrial partners, the knowledge generated in this project can certainly be useful to other Canadian industries by contributing to the improvement of the wear resistance of critical parts ubiquitous to the energy, aeronautics and mining industries. Several other mining equipment suffer from similar degradation to some extent. The interest of Quebec governments for developing the northern territories, which is essentially based on mining activities, will certainly also offer opportunities for applying the knowledge generated in this project.
