Coating compositions, methods to produce non-stick surfaces and non-stick surfaces made therefrom

A method of producing a non-stick coating on a surface of a metallic material, the method comprising:

• producing on top of and in contact with the surface of the metallic material, an intermediate layer which is one of nitriding layer, nitrocarburization layer, and carburization layer on the surface of a metallic material by one of ion plasma nitriding, gas nitriding, and salt bath nitriding methods;
• and
• producing one or more layers of diamond-like carbon containing silicon and oxygen on top of and in contact with one of the nitriding layer, the nitrocarburization layer, and the carburization layer by a plasma enhanced chemical vapor deposition (PECVD) vacuum process.

An article comprising a surface containing one or more layers of DLC containing silicon and oxygen.

An article comprising a surface containing a nitrocarburized layer;

• and one or more layers of DLC containing silicon and oxygen on top of and in contact with the nitrocarburized layer.
