GM has issued a press release saying that it has come up with a way to make brake rotors become rust resistant and stay shiny for a long time by “changing the chemical makeup of the components using a process that could double the life of rotors and save consumers hundreds of dollars.”
Their engineers created a process in which the rotors are heated to 560 degrees Celsius for a day in an atmosphere enriched with nitrogen, which then bonds to the metal, creating a stronger finish. The name for the technology is Ferritic Nitro-Carburizing (FNC), a process used in powertrain parts in the past.

FNC rotor technology is featured on the Buick Lacrosse and Regal as well as on the Chevrolet Malibu, Impala and Volt in North America.
