About
Saeid Heidarinassab
Postgraduate Researcher
DCU
Saeid is a Ph.D. researcher in the Advanced Metallic System Centre for Doctoral Training (AMSCDT) based at I-Form DCU. His research is in the area of laser synthesis and automation. He completed his master’s in materials science and engineering in Iran with a focus on corrosion and surface engineering. After graduating, he worked at the Islamic Azad University of Science and Research in Iran and the Silesian University of Technology in Poland as a research assistant. His main research interests are in the area of laser synthesis, corrosion, and surface engineering.
Research Interests (Lay Summary)
Saeid Started his Ph.D. in I-Form in 2022 and his project consists of two parts. In the first part, he is investigating the properties of novel coatings which can be used for heat absorption/conduction applications. These coatings are being produced using a pulsed laser ablation in liquid technique and will be used as a backing material for abrasive discs to absorb the generated heat during grinding, polishing, and surface finishing, which makes the disc last longer.
The second part of his project is the development of an online vision-based quality control system for the process. In this part, a high-resolution camera will be installed to capture the features of the products, then an image-processing method will be developed using LabVIEW software for automation and control purposes.
Technical Summary
The aim of this project is to gain an understanding of how different process parameters (i.e. laser spot size, laser fluence, scanning speed, pulse repetition rate) will influence the properties of a specific coating and its impact on thermal conduction. Normally, as the abrasive generates heat during the process, some coolants like water, oil, etc are being used to reduce the temperature in the affected zone. To increase the efficiency and sustainability of the process, the project will develop a backing material which absorbs the generated heat and conducts it from the affected zone to the atmosphere without wasting coolant as well as making the abrasive last longer.
The second part of this project is to focus on an online vision-based quality control system for a partner organisation to apply the proposed solution.
