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.

该项目旨在开发具有高抗氧化性、耐腐蚀性和耐磨性的新型涂层材料，以满足在腐蚀性环境中严重侵蚀和磨损条件下运行的发电设备的特定需求。提出了一种可能的解决方案，即提供一种基于改性铁铝化物基体的涂层，在该涂层中原位形成硼化物硬质颗粒以提高其耐磨性。这样的涂层被设计和工程化用于新部件上的应用或磨损部件的抛光。选择和优化涂层配方以满足机械和化学要求，同时选择和优化涂覆方法以实现最大的材料性能，同时考虑技术和经济因素。除了为我们的工业合作伙伴带来直接利益外，该项目所产生的知识肯定对加拿大其他行业也很有用，有助于提高能源、航空和采矿业中无处不在的关键部件的耐磨性。其他几种采矿设备在某种程度上也有类似的退化。魁北克政府对开发主要以采矿活动为基础的北方领土的兴趣，当然也将为应用该项目产生的知识提供机会。
