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

该项目旨在开发具有高氧化性，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基的涂层，其中硼化物硬颗粒在原位形成，以提高其耐磨性。这种涂层的设计和工程要么应用于新零件或翻新磨损的零件。选择和优化涂层配方以满足机械和化学要求，同时考虑技术和经济因素，选择和优化应用方法以实现最大的材料性能。除了对我们的工业合作伙伴的直接好处之外，该项目所产生的知识当然可以通过有助于提高能源，航空和采矿行业普遍存在的关键部件的耐磨性来对加拿大其他行业有用。其他一些采矿设备在某种程度上也有类似的退化。魁北克省政府对开发北部地区的兴趣主要基于采矿活动，这当然也将为应用该项目产生的知识提供机会。

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.
