Biography

Francesco Delloro is a researcher specializing in thermal spraying processes and advanced materials, with significant expertise in the field of cold spray. His research focuses primarily on optimizing the mechanical and microstructural properties of metal and composite coatings, applied to various sectors such as aerospace, automotive, and particle accelerators. His studies address key topics such as the influence of heat treatments on the microstructure of metal powders (e.g., AA7075 alloy), the adhesion of metallic coatings to polymer or composite substrates, as well as the numerical modeling of particle impacts to understand the mechanisms of porosity formation and the mechanical properties of deposits. Delloro has also contributed to methodological innovations, notably the use of advanced techniques such as 3D microtomography, finite element simulation, and machine learning analysis to characterize surfaces and interfaces. His research aims to improve material performance under extreme conditions, while developing processes suited to industrial requirements.

General Engineering Professions (MIG)

Lecturer

A MIG is a personalized, project-based learning program that brings together a group of 12 or 14 students, guided by the School’s faculty members, to explore a complex problem in its various dimensions—including, of course, scientific and technical aspects, but also cross-disciplinary aspects (socioeconomics, management, law, the environment, etc., depending on the field being studied). Ten different topics are offered. They all reflect current research themes being developed by the School’s centers and industry. The challenges students will tackle through these 10 projects address major issues facing the industry of the future and society: From Energy Resource Transformation to Management, Data Science and Innovative Applications, Raw Material Extraction and Environmental Impact, Design and Materials for the Aerospace and Automotive Industries, and Medical and Hospital Care Engineering Each MIG topic is addressed through complementary and interlinked activities during an intensive three-week period: - company visits, lectures, and classes - a period of experimentation and/or modeling at a research center or in a company, in the form of mini-projects carried out in small groups. In addition, each group of students collectively summarizes the work completed in the form of a written report and an oral presentation before a panel of industry professionals. This presentation will allow you to better understand all aspects of the topic and to deepen your teamwork skills.

Guest Lecturer

The curriculum for the course days is as follows: General introduction to additive manufacturing processes; overview of the phenomena involved in LBM and ColdSpray processes; thermodynamics; phase transformation during rapid solidification; associated microstructural evolution; mechanical behavior and properties of parts produced by additive manufacturing processes; post-processing; defect mitigation. LBM and ColdSpray fabrication techniques, construction steps, overview of experimental characterization methodologies related to additive manufacturing processes and defect analysis, measurement of residual stresses using X-ray diffraction (XRD). Numerical modeling of additive manufacturing processes; objectives of simulation tool development; physical phenomena monitored; resolution scales; prediction of final properties. Presentation (by an industry R&D engineer) on the use of additive manufacturing processes in an industrial context, the objectives pursued, and the expected results. In addition to these lectures, a project component will also be included in the course, lasting 6 hours, at the Materials Center (CMAT, Evry), requiring students to travel to this laboratory for two full days. During these two days, on the first morning, students will attend the lecture on fabrication and characterization techniques associated with additive processes (Session V—3 hours in the morning on Day 1). The subsequent training period (3 hours in the afternoon on Day 1 + 3 hours in the morning on Day 2) will be dedicated to carrying out the supervised projects. Independent work (3 hours in the afternoon on Day 2) may be conducted at the CMAT to allow for the review and analysis of the results, in preparation for the evaluation session. Project selections will be made no later than during the first lecture session.
