Bulk Surface Treatment

Mechanofuse® Self-Fluxing Powders

The Mechanofuse® series includes Nickel-based (SFN) and Iron-based (SF6) powders, specifically developed for thermal spray and fuse applications. Produced via a proprietary mechano-chemical process, these powders form fully dense, metallurgically bonded coatings reinforced with hard ceramic phases, offering excellent wear, abrasion, and corrosion resistance. SFN delivers high-thickness coatings (up to 2 mm), with a composite microstructure of ceramics (1600 HV) and a tough Ni matrix (600 HV), achieving 58–63 HRC hardness. SF6, a cost-effective and sustainable Fe-based alternative, offers higher hardness (66–70 HRC) and improved toughness. Applications include hydraulic cylinders, rotors, valves, sleeves, and high-load sliding components. Suitable for combustion flame, HVOF/HVAF, and plasma spray, with fusing via torch, controlled atmosphere furnace, or induction. Mechanofuse® coatings are ideal for extending the life of industrial components operating in severe mechanical and chemical environments.

Thermal Spraying Lab

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: - Wear and erosion resistance - Corrosion and chemical resistance - High-temperature durability - Impact resistance Moreover, coatings can be engineered to add functional properties, such as: - Self-lubrication - Thermal insulation - Tailored friction behavior - Electrical or thermal conductivity 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 32m 2 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: - High spray rates and deposition efficiency - Reduced oxidation and minimal thermal degradation - Lower application costs compared to conventional methods MBN’s TSLab is your partner in transforming surfaces into high-performance functional systems.
