Apple is researching a new scratch-proof coating, presumably for its mobile devices, that would prevent scratches.
The U.S. Patent and Trademark office published new application filed by Apple for “Nitriding Stainless Steel for Consumer Electronic Products” that describes a new system that avoid scratches by placing a layer of nitride over 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... 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.
Apple acquired LiquidMetal in August 2010 gaining the technology behind a new metallic/glass substance that has twice the strength of Titanium but that can be molded like plastics.
