Title:NITRIDING STAINLESS STEEL FOR CONSUMER ELECTRONIC PRODUCTS
Filing Date:2010.4.6.
Application Date:2010.10.28.
Abstract:
A cost effective system, method and apparatus adapted to provide a nitride layer on stainless steel used for the manufacture of consumer electronic products. 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.
