Abstract

In example implementations, a method for producing a coating is provided. The method includes placing a magnesium substrate into an anodizing bath, applying a voltage for a first amount of time to form a micro-porous anodizing layer having a thickness of between 1 to 50 microns on the magnesium substrate, placing the magnesium substrate with the micro-porous anodizing layer in plating bath, wherein the plating bath comprises a metal and a complexing agent with a pH between 8 and 14, applying a first current to the plating bath for a second amount of time to form an interlock layer on the micro-porous anodizing layer, and applying a second current to the plating bath for a third amount of time to form a coating on the interlock layer.

Abstract

In example implementations, a method for coloring an alloy is provided. The method includes anodizing a substrate in an anodizing bath comprising phosphoric acid, at a constant temperature and a constant voltage for a first time period to develop an anodizing layer that includes a barrier layer, reducing the constant voltage applied to the anodizing bath for a second time period to change a thickness of the barrier layer and change a width of pores in the anodizing layer, plating the substrate in a plating bath at a first current that is increased over a third time period in accordance with a current profile of the plating bath, and plating the substrate in the plating bath at a second current for a fourth time period.

Abstract

The present invention relates to a method for producing a polymer, polymers and metal-polymer composites produced by the method. The method comprises providing one or more polymerisable monomers and providing a substrate comprising an activated metal surface, the activated metal surface comprising one or more compounds capable of initiating polymerisation of the one or more polymerisable monomers. The method comprises contacting the activated metal surface and the one or more polymerisable monomers to polymerise the one or more polymerisable monomers, thereby producing the polymer.
