Cold Spray and Rapid Deposition (ColRAD)

🎉 Excited to announce the publication of our latest research in Coatings titled "Machine-Learning-Driven Optimization of Cold Spray Process Parameters: Robust Inverse Analysis for Higher Deposition Efficiency"! In this study, we tackled a persistent challenge in cold spray technology: optimizing deposition efficiency (DE). Using a novel two-stage machine learning framework combined with Bayesian optimization, we accurately predicted DE and identified optimal process parameters for efficient material deposition. 🔑 Key Findings: - AI-Driven Efficiency: Our approach highlighted the influence of key factors like gas type, temperature, and pressure on deposition outcomes. - Hydrogen's Potential: We demonstrated that using hydrogen as a carrier gas can lower operational costs while achieving high DE. - Explainable AI (XAI): SHAP analysis provided interpretability, showing gas temperature and type as dominant contributors to DE. - Real-World Validation: The model achieved high accuracy, replicating experimental conditions and offering valuable insights for cost-effective, high-performance cold spray processes. 👉 Read more here: https://lnkd.in/e6ffEYbs Special thanks to: Aditya Medarametla Denny John Arvind Agarwal, head of the Cold Spray and Rapid Deposition (ColRAD) Lab at Florida International University, provided invaluable guidance and expertise for this research.

New Patent on Cold Spray Technology for Power Electronics! Traditionally, cold spray has been used to create dense and hard coatings for repair and refurbishment of aerospace components. This patent addresses development of large area capacitators for power electronics using thin and "porous" Aluminum coatings. Cold spayed porous Aluminum coatings had a 9 times enhanced surface area which significantly boosted capacitance density by 20 times as compared to the planar capacitors. This novel application of Cold Spray can lead to next generation of power electronics, enabling enhanced efficiency and more compact designs in industries like telecommunications, automotive, and energy. This was possible due to the collaborative efforts with Prof. Markondeya Raj Pulugurtha and his team member Reshmi Banerjee. Congratulations to Denny John and Cheng Zhang, Ph.D. from Cold Spray and Rapid Deposition (ColRAD) laboratory to make this happen.

🌟 Congratulations to Dr. Kazue Orikasa on successfully defending her Ph.D. dissertation! 🌟 It's been a privilege to watch Kazue grow since joining our research group in 2019 as an undergraduate researcher. As an undergraduate, she started working on the mechanical properties of soft materials and even co-invented a U.S. patent. Kazue’s journey has been remarkable, marked by her selection as a NASA NSTGRO Fellow and culminating in her groundbreaking doctoral research on BNNT/BNNP Foam-Polymer Composites for thermal management and radiation shielding. Throughout her Ph.D. journey, Kazue has published six (6) journal articles as lead author and is a co-inventor on four (4) additional U.S. patents. Her innovative research is truly out of this world, with her polymer-BNNT/BNNP composite samples soon to be tested aboard the International Space Station as part of MISSE 20 experiments. The SpX-31 launch is set for November 5, and we couldn’t be more excited! Congratulations, Dr. Kazue Orikasa! We are incredibly proud of your achievements and can’t wait to see what’s next. A big thank you to our collaborator, Dr. Cheol Park, at NASA Langley Research Center, for being an integral part of this journey.
