New Apple patent application for Scratch Resistant Stainless Steel

A new patent application from Apple reveals stainless steel electronic devices that are more durable and scratch resistant. The application entitled entitled "Nitriding Stainless Steel for Consumer Electronic Products" describes a cost-effective system that would place a layer of nitride atop a stainless steel exterior.

“In addition to providing a durable, hard surface that is both scratch and impact resistant, the nitride layer allows for the natural surface color and texture of the underlying stainless steel to remain visible to the user,” says the patent. “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.”
