Abstract

The present invention relates to a chain link plate with bright and colourful surface and its production method. Said chain link plate includes a chain link plate self-body and a colour covering unit, in which the colour covering unit is plated on one surface of said chain link plate self-body by adopting arc discharge ion plating process. The above-mentioned colour covering unit can be single basis layer or also contains several colour-developing layers, in which the basis layer is selected from the materials of titanium nitride, zinc nitride and zirconium nitride etc, and the colour-developing layer can be selected from the materials of titanium oxynitride, zinc oxynitride and zirconium oxynitride, etc.

Description

【Technical field】 [0001] The present invention relates to a chain piece and a manufacturing method of the chain piece, in particular to a manufacturing method for forming brilliant colors on the surface of the chain piece by physical vapor deposition, and the chain piece with brilliant colors on the surface. 【Background technique】 [0002] For a long time in the technical field of chains, in order to take into account the safety of chain operation, metal materials are used to manufacture chain parts, and the structural strength of parts is improved through heat treatment. Sometimes in order to achieve the purpose of rust prevention or safety, for example, The surface of parts such as chain pieces is electroplated or coated with reflective paint, and the electroplating layer attached to the surface of the chain piece by electroplating is easy to lose its function due to rapid wear and tear due to the relative pivoting between parts. It has a safety effect in the initial use, ...
