General Motors (GM) has introduced a groundbreaking technology known as Ferritic Nitro-Carburizing (FNC) that promises to significantly reduce brake rotor corrosion and extend their lifespan. This innovation is set to save vehicle owners substantial amounts of money and improve overall vehicle performance.
GM's new Ferritic Nitro-Carburizing (FNC) technology is revolutionizing brake systems by significantly reducing corrosion and doubling the lifespan of brake rotors. This innovation, developed by GM engineers, involves superheating rotors in a nitrogen-filled oven, making them more durable and efficient. Since its introduction, FNC has reduced brake-related warranty claims by 70% and is expected to be a standard feature in most GM vehicles by 2016.
Brake rotor corrosion has long been a significant issue for vehicle owners, particularly in regions with harsh environmental conditions. Factors such as acid rain, snow, ice, and road salt contribute to the oxidation and eventual rusting of brake components. According to a study by GM, 40% of vehicle owners listed corrosion as one of their top three concerns, with brake parts being a primary focus.
FNC is a process that involves superheating brake rotors in a nitrogen-filled oven. This causes nitrogen atoms to bond with the rotor surface, creating a hardened, corrosion-resistant layer. This innovative treatment not only prevents rust but also enhances the overall durability and performance of the brakes.
GM engineers have been perfecting FNC technology since 2008. In extensive testing, vehicles equipped with FNC-treated rotors showed a 70% reduction in brake-related warranty claims. This significant improvement underscores the effectiveness of the technology in real-world conditions.
FNC-treated rotors offer several advantages:
As of now, FNC technology is available in models such as the Buick LaCrosse and Buick Regal. GM plans to make FNC a standard feature in the majority of its vehicles by the 2016 model year.
GM is currently the only automaker utilizing FNC technology for brake rotors, holding several patents for the process. This innovation is part of GM's broader strategy to lead in automotive advancements, as recognized by the U.S. Patent Board.
Jim Webster, the technical expert behind the FNC project, emphasized the importance of addressing oxidation caused by environmental factors. "Rotors aren’t a cheap thing to replace," Webster noted. "Doubling the average life expectancy of the brake rotors from 40,000 to 80,000 miles is something we think our customers will appreciate."
John Calabrese, GM's vice president of Global Vehicle Engineering, echoed this sentiment, stating, "GM engineers are pushing forward with innovative technologies that meet the demanding needs of our customers."
GM's Ferritic Nitro-Carburizing technology represents a significant leap forward in automotive engineering. By addressing the pervasive issue of brake rotor corrosion, FNC not only enhances vehicle performance but also offers substantial cost savings for consumers. As GM continues to innovate, the future of automotive technology looks promising.

Cutting Off Access for Oral Bacteria May Be Key to Preventing Tooth Decay
The journal of Microbiology recently published a study containing results which suggest that we may now have the keys to preventing gum disease and tooth loss. The study says that if we can strip some oral bacteria from being able to access the other pathogenic oral bacteria then we may be able to use them to help prevent decay and loss.
New Oversight Means New Rules for Credit Collectors
Recently a major consumer finance watchdog released reports that the government has plans to regulate previously unregulated financial firms. Now these debt collectors and credit reporting agencies are preparing themselves for the worst.
Green Beer? Try Green Teeth
This Saint Patrick’s Day thousands of people across the U.S. will be going out to celebrate with lots of delicious green foods like green cakes, green cupcakes, green chocolate, green eggs and ham, and even the popular Saint Patty’s Day hit green beer. But all this green food has one thing in common: green food coloring. In small doses green food coloring can be a fun way to brighten up your food or play along for Saint Patrick’s Day, but after eating green food coloring all day a person’s teeth will quickly start to show that green dye.
