Synthetic Sulfides for Friction Materials
Sulfides are key additives for adjusting some critical aspects of the pad/rotor performance, wear and comfort, because its ability of interacting with the phenolic resin degradation and to the tribochemistry of the pad interface. But also they are becoming key additives for other applications like green energy (batteries, green hydrogen and solar panels) and other applications like powder metallurgy.
We have spent years understanding the effect in the tribochemistry of sulfides and mastering our production technology to offer an innovative but proven concept to the friction community with OE quality and the best value-for-money that allows every customer to get rid of the instability associated with the usage of legacy sulfides.
Thanks to their unique microstructure we can modify the oxidation temperature range of our composites, and match the oxidation temperature range of legacy Tin based products. Our products differently react than the mechanical mixes, and this have effect on the performance and wear. And now we are ready to bring the benefits of advanced sulfides to other industries.
Synthetic Sulfides for Powder Metallurgy
FE70 is pure synthetic iron (II) sulfide. It is softer, has higher thermal stability and more cohesive physical and chemical properties compared to natural pyrites.
Sintered powder metallurgy parts are of distinguished importance in today's world. Machining of the relatively hard sinter hardened parts is difficult, and for years manganese sulphide particles has help on the chip formation during turning, but with drawback in terms of cost and safety.
Mastering synthetic sulfide production we now offer ost effective and Safe alternatives to Manganese Sulfide to improve the machinability of steels, aiming at obtaining longer tool life and smother surface finish of PM steels
Fiber-free Potassium Magnesium Titanate
Our production process is very stable and efficient to produce a high quality and cost-effective fiber-safe titanate because it doesn't make fibers while synthesized. KMT24 Fiber Free Potassium Magnesium Titanate is a crystalline ceramic material with high dielectric constant and low thermal conductivity properties.
KMT24 can be used in brake pads for its catalytic properties towards phenolic resin favoring the formation of low molecular weight byproducts and avoiding sticky residues, contributing to stabilize COF (improve μ stability), reduce the wear and improve NVH properties.
Lithium titanate (LTO) replaces the graphite in the anode of a standard lithium-ion battery and it can be used in combination with LMO or NMC cathode. When compared with conventional Li-ion with graphite anode, LTO avoids the SEI film formation and lithium plating when fast charging and charging at low temperature. Moreover, LTO powder prevents the occurrence of aluminum alloying, which in turn enables the aluminum current collector to generate a significantly enhanced gravimetric capacity compared to copper.
Innovamat's LIT powders consists of LTO particles that are available both in micro and ultrafine partilcle size. Our LTO manufacturing process is versatile and allows modifications to the composition, morphology, and particle size. As a result, the material can be tailored to meet the needs of the specific application.
MMC powders for EHLA
The European Commission has committed to reducing current emission limits in vehicles, from all sources. Brake wear is a significant contributor to respirable particulate matter (PM10 and PM2.5), particularly in areas with high traffic density and frequent braking, and up to an 80% of these particles may come from the wear of the rotor (Grey Cast Iron).
Technologies like hard coated rotors, focus on eliminating the source of the problem, the particles themselves, through the introduction of a wear resistant coating on top of the gray cast iron of the rotor. Traditional coating technologies like nitrocarburizing may be bring concerns on the long terms with Low Steel formulas, due to its small thickness and thick diffusion layer. New technologies like EHLA (Extra High Speed Laser Cladding) may be the ideal solution. Because of the relation between wear resistance and friction stability with contect of hard particles, MMC coating (metal matrix ceramic composites) are the best technological choice, on top the precipitation hardening alloys that are not able to achieve such a high percentage of ceramic phase. But usually those MMC powders are based on strategic metals like W and Co. In innovamat we have introduced our range of TCF green carbide MMC based powders, based on TiC, that use no strategic metal in the metal matrix and are designed for application on brake rotor with EHLA, allowing users to achieve the higher percentaje of ceramic reinforcement in their coating.
