ATOMIC FORGING AND‘ FOREVER’ BRAKES
Carbon ceramic is the gold standard for brakes. But what about nanotech-enhanced iron brakes?
One way to optimise brake performance within the given constraints of wheel size and wheel corner packaging on vehicles is to use advanced materials. Steel was once the standard for high-performance brakes, but ceramics and carbon composites offer better thermal dissipation, though they have their own challenges with operating temperatures and noise.
But what if there was a brake technology that didn’ t require larger brake rotors, worked within current packaging constraints, and didn’ t have to use exotic rotor materials? PureForge is an American engineering company with advanced patents that promise to extend OEM brake rotor life by 1000 %.
In a global automotive market where all vehicles are growing increasingly heavier, especially EVs and PHEVs with batteries adding significant weight, the idea of a brake surface treatment that could enhance brake rotor life by 1000 % is notable.
PureForge claims that its technology can make brake systems, both rotors and pads, last more than three times the average lifetime of a normal passenger vehicle ownership cycle, about 300 000km. It’ s an impressive claim, but how do they do it? By using atomic-forged nanotechnology.
Nanotech brake knowledge
Brake system engineers and technicians know that rotor surface texture and brake pad material science are what enable the friction-to-heat conversion. But the latest nanotechnology and chemical engineering processes allow technicians to control the deposition of materials and coatings on rotors and pads to a scale unimaginable a decade ago.
What PureForge does is use physical vapour deposition, a familiar technology in the semiconductor industry, but one that PureForge has applied to brakes. What physical vapour deposition does is penetrate and change the metallurgical structure of traditional cast iron rotors.
Atomic forging is a deep metallurgical technology. It works on a nanotech scale, improving the integrity of brake rotor material at the molecular level, where engineers had historically accepted that changes could not be made. PureForge’ s process creates iron brake rotors with nearly wear-resistant surfaces. It’ s the theoretical physics dream of brake design – simple iron brake rotors that suffer less abrasive wear. Matched with Purge Forge’ s pads, these Atomic Forged brake components also reduce brake dust by 70 %, last many times longer than conventional iron or steel brakes, and have superior corrosion resistance. That solves a problem for fleet managers who have vehicles that often overnight in a depot without cover, exposed to dewpoint moisture. Or any vehicle owners who live near the ocean.
PureForge has signed a development contract with Hyundai and is already supplying several American government agencies and commercial fleets. These nanotech-enhanced iron brake rotors, with performance and durability that far exceed industry standards, prove that legacy automotive component metals have much more potential when nanotechnology is applied.
