Funding Authority Romanian National Authority for Scientific Research CNCS – UEFISCDI Romania- China bilateral projects PROJECT OUTLINES Host Institutions: Politehnica University of Timisoara Objectives University of Science and Technology Beijing Research Results Collaborations Sinterization of novel structures for alloys with increased functionality Contact Ctr. No. PN-III-P 3 -3. 1 -PM-RO-CN-2018 -0027

Collaboration aim The collaborative research, based on the complementary experience of the two groups

Collaboration aim The collaborative research, based on the complementary experience of the two groups aims to design and manufacture sintered materials (including porous or with gradient) belonging to the intelligent materials class of materials, with the primary focus on Ni. Ti based alloys. The collaboration will use both the experience of the research groups in Romania and China, as well as the scientific research infrastructure in the partner’s institutions for the development of new technologies in order to manufacture high-performance intelligent materials, with wide potential use, ranging from the biomedical to the automotive industry. Both sides will conduct cooperative research activities in order to achieve the objectives of the project. The subject of collaboration is topical in both partner countries and the European Union, leading to the possibility of achieving advanced materials with improved functionality and potential for use in biomedical applications.
