A process for surface modification of a component includes providing a first reactor for a main procedure and a second reactor for an ancillary procedure. The first reactor is charged with a main medium, a component is provided to the first reactor, and the main procedure is performed by bathing the component in the main medium to bring about a chemical change onto a surface of the component. The second reactor is charged with an ancillary medium, the component is provided to the second reactor, and the ancillary procedure is performed by bathing the component in the ancillary medium to treat the surface of the component. The chemical change is a surface modification that takes the form of bluing or phosphatizing, the surface modification forms a conversion coating, and the component has a diameter or dimensions in the range from 0.5 m to 12 m.
