PD 39 Project
English (Engleză) Project number: PN-III-P1-1.1-PD-2021-0363 Project title: In situ monitoring of additive manufactured parts via infrared thermography and high speed imaging Financial support: Romanian National Authority for Scientific Research and Innovation, CNCS-UEFISCDI Periode: April 2022 - March 2024 Contact Person: Project Director: Dr. Ing. Diana CHIOIBASU Coordinator: National Institute for Laser, Plasma and Radiation Physics - I.N.F.L.P.R. Atomiștilor 409, Măgurele, Romania Abstract:
Metal matrix composites are materials made up of at least two elements: a majority metal phase and a ceramic material in the form of particles or wires, dispersed in its mass. They benefit from the properties of the metallic material, such as low mass, high elasticity or high biocompatibility, to which are added other superior properties such as high breaking strength, better coefficient of friction or higher thermal conductivity, determined by the dispersed phase of the ceramic material. In this project, we will manufacture composite components using a 3D printing method entitled Laser Melting Deposition (LMD). The precursor material will be composed of metallic powder mixed in different mass concentrations with a hard ceramic. The objective of the proposed project is to understand and optimize the deposition process by monitoring it in real time using thermal and high speed imaging cameras. The results will allow to correlate the temperature distribution and / or plasma intensity, with internal defects that may form/appear during processing such as pores, cracks, flowing material or poor homogeneity of the elements of metal matrix composite. The development of such a monitoring system will result in an increase of the spatial printing resolution and will ensure the repeatability of the process, which represents a huge problem of the LMD technique.
Project objective:
The main objective of this project is to develop a set-up that allows real time monitoring the MMC fabrication parts, which allows early detection of defects during LMD process. With such a monitoring device, the user can interrupt the process early if flaws are detected and can help identify the cause of the defects, thus reducing the number of trial and error experiments.
Estimated results:
- 2 ISI articles
- 2 oral presentations at international conferences
- 1 national patent application

Română (Romanian) Numar proiect: PN-III-P1-1.1-PD-2021-0363 Titlul proiectului: Fabricatie aditiva monitorizata in timp real prin termografie si imagistica rapida de componente din materiale compozite cu matrice metalica Suport financiar: Autoritatea Nationala Romana pentru Cercetare Stiintifica si Inovare, CNCS-UEFISCDI Perioada: Aprilie 2022 – Martie 2024 Persoana de contact: Director de proiect: Dr. Ing. Diana CHIOIBASU Coordonator: Institutul National pentru Fizica Laserilor, Plasmei si Radiatiei – I.N.F.L.P.R Atomiștilor 409, Măgurele, Romania Abstract:
Compozitele cu matrice metalica sunt materiale formate din cel putin doua elemente: o faza metalica majoritara si un material ceramic sub forma de particule sau fire, dispersat in masa acesteia. Ele beneficiaza de proprietatile materialului metalic, precum masa redusa, elasticitate mare sau biocompatibilitate ridicata, la care se adauga si alte proprietati cu rol determinat de faza dispersata precum rezistenta ridicata la rupere, coeficient mai bun de frecare sau conductivitate termica superioara. In acest proiect, vom fabrica componente din materiale compozite utilizand o metoda de imprimare 3D denumita Depunere Laser prin Topire. Materialul precursor va fi compus din pulbere metalica amestecata in diferite proportii cu o ceramica dura. Obiectivul proiectului este intelegerea si optimizarea procesului de depunere prin monitorizarea lui in timp real cu ajutorul unor camere termice si prin imagistica rapida. Rezultatele vor permite corelarea distributiei de temperatura si/sau intensitatea plasmei, cu defecte de interior care pot aparea in timpul procesarilor precum, pori, fisuri, material care incepe sa curga sau neomogenitati ale elementelor din care este compus compozitul cu matrice metalica. Dezvoltarea unui astfel de sistem de monitorizare va permite cresterea rezolutiei spatiale de imprimare si va asigura repetabilitatea procesului.
Obiectivul proiectului:
Obiectivul principal al acestui proiect este de a dezvolta un mecanism de corelare a defectelor ce pot aparea in timpul procesului de fabricatie aditiva de piese din materiale compozite cu matrice metalica cu fluctuatiile inregistrare prin intermediul unor camere termice si a unei camerei rapide. Utilizand aceasta metoda, procesul poate fi intrerupt inca dintr-un stadiu incipient daca sunt identificate variatii ale temperaturilor sau plasmei care ulterior pot conduce la defecte in structura pieselor fabricate, astfel se reduce numarul de experimente nereusite.
Rezultate estimate:
- 2 articole stiintifice
- 2 prezentari orale la conferinte internationale
- 1 cerere de brevet de inventie
