Installation for the obtainment of light biocompatible high-purity alloys through levitation in an inert atmosphere
Contract No.: 14 PTE/2016
The general purpose of the project is the development and production of an installation for the obtainment of light biocompatible high-purity alloys, through electromagnetic levitation in an argon inert atmosphere. The functionality of the installation will be also verified through tests and through the attempt to obtain a class of light biocompatible alloys from the Mg-Ca alloy system, which can be used for bioresorbable implants. Therewith, the exploitation of the results is pursued by implementing the innovative solution in production for the applicant, for distribution on the internal or external market, considering the applicant’s commercial relationships and prestige (over 75% of the equipment production is for export). The intellectual property rights over the results will be protected by invention patent and the partners will specify exactly each part’s participation percentage and the conditions of the technological transfer of the results in a collaboration agreement that will be issued before the project start.

Activity 4 – Production project of the installation for the obtainment through levitation of light metallic alloys
Activity 5 – Webpage development
The construction of the levitation melting installation, the obtainment and description of the light high-purity alloys from the Mg-Ca system
Activity 2.2 – Industrial research carried out by the coordinator of AAGES S.A. from Sângeorgiu de Mureș
An experiment of levitation melting was carried out and the light metals obtained were cast into molds.
The geometry of the inductor was optimised, in order to be adequate for melting magnesium alloys.
The parameters of the levitation melting PROTOTYPE were set.
Considering the innovative aspect of the project and the established working conditions, the need to build a SUPPORT STAND was identified, auxiliary to the levitation melting installation, geared with the equipment, machines and instruments specific for the research theme.
Activity 2.7 – The dissemination of the results on a large scale, through communication and national and international publication by Partener P1 – Polytechnic University of Bucharest
The partial results were included in the published work ”Designing and obtaining of new metallic alloys”, by prof. Dr. Engr. Victor GEANTĂ, on Day of Macedonian Metallurgists in Skopje, on 7 May 2017.
