Originally filed on April 6, 2010, a recently published patent application from Apple indicates that the company might consider using a nitride coating on its products to make them more durable and less prone to scratching.
Titled “Nitriding Stainless Steel for Consumer Electronic Products”, the patent application describes a process whereby a thin layer of nitride would be applied on top of a device’s stainless steel exterior to help it maintain its sheen over the course of time.
“In addition to providing a durable, hard surface that is both scratch and impact resistant,” the patent reads, “the nitride layer allows for the natural surface color and texture of the underlying stainless steel to remain visible to the user. It is this natural surface color and texture of the stainless steel that adds to the aesthetically pleasing appearance of the consumer electronic product, thereby enhancing the user’s overall experience.”
For anyone who remembers how scratched up the old school iPods used to get, or hell, even the current iPod Touchs, it’s nice to see Apple is constantly looking for ways to maintain the aesthetic it’s so famous for.
