PhD Candidate Nguyen Hong Tien presented a summary report of his research before the Committee

The research of PhD Candidate Nguyen Hong Tien has contributed a highly applicable scientific approach to the design and improvement of industrial extrusion screws. In the coming time, the candidate proposes focusing on three main development directions: Optimizing HVOF thermal spraying technology with new material systems to adapt to harsh conditions; Applying artificial intelligence and optimization algorithms to automate geometric design and predict wear; and conducting experiments on various raw materials and load capacities. In particular, the development of smart extrusion screws integrated with sensors will facilitate predictive monitoring and maintenance, thereby maximizing the efficiency and reliability of production systems.
