Problems solved by technology

[0008] Sputter coating techniques can also be used to plate chrome on molds, but again, these techniques produce uneven, low-density deposits that can become sticky initially or over time , as a result, the plastic substance is difficult to release from the mold

Embodiment Construction

[0061] Exemplary, non-limiting aspects of metallization methods and metallization materials are disclosed herein. The disclosed features relate to coatings, methods of coating and their use, the coatings being based on alternating metal and metal-gas compound coatings. Disclosed features also relate to the use of filtered cathodic vacuum arc (FCVA) techniques for metal-gas compound coatings, and combinations of these features.

[0062] The gas may contain one or more atoms selected from nitrogen (N), oxygen (O), hydrogen (H), sulfur (S) and mixtures thereof. The gas may be in the form of a pure gas such as pure nitrogen (N 2 ), hydrogen (H 2 ) or oxygen (O 2 ), alternatively, the gas may contain molecules of gas atoms. Exemplary molecules of gas atoms include ammonia, nitrogen oxides, sulfur oxides, nitrous oxide, and hydrogen sulfide.

[0063] Preferably, the metal-gas compound is a compound of a metal and one or more gas atoms. A feature of the invention is that the ga...

Abstract

A method of forming a metal coating comprising the steps of: (a) generating an arc at a metal target to create metal ions in a chamber that is under vacuum or has an inert atmosphere; (b) depositing the metal ions on a substrate to form a metal layer thereon; and (c) controlling an amount of gas in the chamber to form a primary metal-gas compound layer on said metal layer and a secondary metal-gas compound layer on said primary metal-gas compound layer, wherein said primary and secondary metal-gas compound layers have different gas atom contents.

Description

technical field [0001] The invention relates to a method of producing a metal coating. In particular, the present invention relates to thin film metal coatings, methods of making thin film metal coatings, and uses and applications of such coatings. Background technique [0002] It is known to manufacture polymers and other plastic materials by cooling the heated polymer or plastic material in liquid phase in a mold to form an object having the shape of the mold. Typically, molds for making plastic objects are made from heat-treated metal. The surface of the mold is coated with various coatings to ensure that the finished plastic object can be successfully released from the mold. One known coating is titanium nitride. [0003] When making epoxy polymers, this polymer tends to stick to the surface of the mold more than other polymers. In order to reduce such sticking, it is known to coat the surface of the mold with a thin layer of metallic chromium. The typical coating m...
