MBN operates a dedicated Thermal Spraying plant, focused on HVAF (High Velocity Air-Fuel) technology. HVAF uses a supersonic, high-temperature gas jet to propel powder particles onto surfaces with exceptional energy, creating strong, dense, and well-adhered coatings. This process is suitable for almost all common thermal spray materials, including cemented carbides, metal alloys, and composite powders.
Thermal spraying is widely used to enhance or restore the surface performance of mechanical components, providing:
Moreover, coatings can be engineered to add functional properties, such as:
Thanks to our deep expertise in powder materials and surface engineering, we support clients in identifying innovative and customized solutions for critical surface applications.
The HVAF plant is equipped with a 32m2 booth with automated 7 interpoled Axes Kuka anthropomorphic robot , capable of handling parts up 3 meter length, 1.5m height and 2.000kg weight mm
We offer technical consulting and feasibility trials to explore the full potential of thermal spraying for each application, pushing the boundaries of what is technically achievable.
HVAF technology ensures:
MBN’s TSLab is your partner in transforming surfaces into high-performance functional systems.
Powders for Additive Manufacturing: From Spray Drying to Sintering
MBN Nanomaterialia develops and optimizes powder feedstocks for Additive Manufacturing (AM) using a complete in-house process chain—from spray drying of agglomerated powders to debinding and sintering of printed parts. This integrated approach enables the production of materials tailored for binder jetting and other AM techniques that require flowable, sinterable powder granules.
The process begins with the formulation of custom powder suspensions, which are then transformed into spherical agglomerates through spray drying. This step allows precise control over particle size distribution, morphology, and flowability—key factors for AM performance.
The agglomerated powders can then be shaped using binder-based AM techniques. Following shaping, debinding removes organic components while maintaining the geometry, and sintering consolidates the structure, ensuring full densification and mechanical strength.
This process route is particularly well-suited for materials that are difficult to atomize or for producing composite powders and nanostructured materials with enhanced properties. It enables the use of non-conventional chemistries and microstructures, opening new possibilities for functional and structural applications in aerospace, energy, tooling, and more.
Thanks to our deep knowledge of powder metallurgy and process integration, MBN can support both material development and application-specific prototyping for advanced AM solutions.
