项目摘要

The main objective of this Alliance International Catalyst project is to initiate the first stage collaboration with two international partners while providing a complementary training environment for students in-term of research subject, expertise, and facilities. The research subject is in-depth corrosion assessment of novel high strength biocompatible alloys for dental implants, by combining three complementary expertise of restorative dentistry, high-entropy alloys, and electrochemical corrosion. This collaboration will address the challenge of attaining a high level assurance of corrosion resistance of implant material that is unachievable by the current standard assessment method. The global importance of understanding the fundamental of corrosion of medical implants is directly related to assuring the health and safety of the patients. Implant failures due to corrosion cause morbidity to the patients, and put a burden to the healthcare expenditure and thus Canadian economy at large. An unnecessary negative impact knowing that these failures are preventable when corrosion resistance of implant materials is assured by a proper in-depth assessment method. The research outcomes could also indirectly benefit Canada as this collaboration provides an excellent training platform to prepare future Canada's highly qualified personnel equipped with both competitive advanced technical and professional skills supportive to innovation and entrepreneurship.

该联盟国际催化剂项目的主要目标是启动与两个国际合作伙伴的第一阶段合作，同时在研究课题、专业知识和设施方面为学生提供互补的培训环境。本课题是结合修复牙科、高熵合金和电化学腐蚀三个互补的专业知识，对新型高强度生物相容性牙种植体合金进行深入的腐蚀评估。此次合作将解决目前标准评估方法无法实现的植入材料高水平耐腐蚀性保证的挑战。了解医疗植入物腐蚀的基本原理对确保患者的健康和安全具有全球重要性。由于腐蚀导致的植入物失效导致患者发病，并给医疗保健支出带来负担，从而给整个加拿大经济带来负担。当通过适当的深入评估方法确保种植材料的耐腐蚀性时，这些故障是可以预防的，这是不必要的负面影响。研究成果也可以间接惠及加拿大，因为这一合作提供了一个良好的培训平台，为未来加拿大培养具有竞争力的先进技术和专业技能的高素质人才，支持创新和创业。
