The goal of this research was to simplify the preparation process of graphene‐contained powder coatings for metal anticorrosion. To do this, thermosetting powder/graphene oxide ([email protected]) composites were prepared via a facile planetary ball‐milling technique and were painted onto tinplates by electrostatic spraying. After immersion in a 3.5 wt % NaCl solution for 9 days, potentiodynamic
Jun 15, 2012 ·ł. The powder of a material is taken inside the steel container. This powder will be made into nanosize using the ball milling technique. A magnet is placed outside the container to provide the pulling force to the material and this magnetic force increases the milling energy when milling container or chamber rotates the metal balls. 3.
