LAYRR's Nano-Coating Breakthrough for Metal Powders

A little late to share this review paper published in Advanced Science but very glad to see it finally out. 🔗 https://lnkd.in/dHM-9UTr This review focuses on multi-principal element alloy (MPEA)-based films and coatings, a rapidly developing materials class with strong potential for extreme-environment applications. We discuss how compositional complexity, nanoscale architecture, heterostructures, and interfacial engineering can be used to regulate microstructure and tailor a wide range of properties, including mechanical performance, wear and erosion resistance, corrosion tolerance, and thermal stability. We also highlight key challenges and future directions, particularly in predictive microstructure control, scalable processing, and the integration of modelling, high-throughput experiments, and machine learning for next-generation materials design. This topic also connects closely with some of the directions we are currently exploring in our group, particularly in magnetron sputtering and electrodeposition of MPEA-based coatings, where precise control of composition and microstructure remains a key challenge. It also links naturally to some of our recent work on deformation mechanisms and kinetics in additively manufactured alloys. Review papers often take a bit of extra time before they finally “meet everyone”, so I’m glad to share this one now. Many thanks to all co-authors for the collaboration and effort behind this work.

#Sustainable and Industry-Ready Metal Matrix #Composites Produced by Stir Casting and Cryorolling: Process–Property Insights Enabled by #Machine #Learning—A #Review by Haitham M. Alswat J. Compos. Sci.2026, 10(2), 95; https://lnkd.in/dCyamZeK Abstract Metal matrix composites (MMCs) are one of the significant engineering materials for many industrial applications. The growing interest in MMCs stems from their strong mechanical properties, including their higher specific mechanical strength and excellent corrosion and wear resistance. From an industrial viewpoint, the ability of MMCs to undergo secondary processing is significant. This review aims to clarify the effects of cryorolling on the microstructure, mechanical properties and wear behavior of different aluminum-based MMCs. In particular, aluminum matrix composites (AMCs) produced through the stir-casting approach experience an additional cryorolling procedure to enhance their tensile mechanical strength and wear resistance. This hybrid manufacturing approach has shown promise in creating effective structural components. This review covers the production of ex situ aluminum-based composites formed by stir casting and then cryorolling. It also highlights how the particle size, volume fraction, and the cryorolling procedure affect the microstructure, wear, and mechanical properties. This approach could broaden the uses of hybrid manufacturing by demonstrating its practical advantages and efficiency. Furthermore, this review highlights the importance of implementing machine learning (ML) models and life cycle assessment (LCA) in evaluating MMCs produced through stir casting.

🔬 New publication: SiC-reinforced coatings via wire laser cladding ⚙️ One challenge in wire laser cladding is producing metal matrix composite (MMC) coatings without using specially manufactured composite wires, which are expensive and difficult to produce for each reinforcement composition. In our latest research, we propose a novel pre-texturing approach that allows SiC particles to be embedded directly into the substrate before cladding, enabling the fabrication of SiC-reinforced 316L coatings using standard wire feedstock. 📊 Key results • Up to 12.2 vol.% SiC incorporated into the clad • Hardness increased from ~170 HV to >330 HV • 40–55% reduction in wear volume • Stable metallurgical bonding with refined microstructure 🏭 Potential industrial applications Wear-resistant surfaces for aerospace, automotive, energy systems, tooling, and component repair. This approach shows how surface engineering combined with additive manufacturing can create reinforced coatings in a simple and scalable way. #AdditiveManufacturing #LaserCladding #MetalMatrixComposites #SurfaceEngineering #Tribology KSF - Institute for Advanced Manufacturing Hochschule Furtwangen Meltio Armin Siahsarani Dr.-Ing.

We are pleased to share our recent research publication on the fabrication of a hybrid AA7075 aluminum matrix composite reinforced with ceria-stabilized tetragonal zirconia polycrystal (Ce-TZP) and SiC-based polymer-derived ceramics (PDC) using a pressure-assisted hot press sintering process. 🔬 Key highlights of the study: • Monolithic AA7075 exhibited an ultimate compressive strength of 620 MPa with 37% ductility, among the highest reported for sintered AA7075. • Hybrid composites containing 4, 8, and 12 wt.% reinforcements were successfully fabricated. • The 8 wt.% reinforced composite demonstrated optimal performance with 113 HV microhardness and 365 MPa compressive yield strength (~35% improvement) over the base alloy. • Microstructural analysis revealed uniform reinforcement distribution, refined equiaxed grains, and strong interfacial bonding. These findings highlight the effectiveness of hot press sintering in developing high-performance AA7075-based hybrid composites for advanced structural applications. 📖 Please feel free to go through the publication for more details.
