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.

Methods, systems and apparatuses are disclosed for treating aluminum desmutting solutions by reacting, mixing and filtering an aluminum desmutting solution flow from an aluminum desmutting solution tank and controlling the amount of copper ions in an aluminum desmutting solution tank by directing a portion of the desmutting solution from a desmutting solution tank to a treatment line, reacting a portion of the desmutting solution in the treatment line and recirculating a filtered aluminum desmutting solution to the aluminum desmutting solution tank during active desmutting operation of the aluminum desmutting solution tank.

A plating apparatus includes a plating tank and a plating unit that performs electrolytic plating on an object. The plating unit includes a workpiece passage region including a partition wall that allows passage of the plating solution but does not allow passage of the object, the workpiece passage region passing the object from above toward below, an injection unit that injects the plating solution from below toward above, a mixing unit that mixes the plating solution injected by the injection unit and the object to be plated passing through the workpiece passage region, an anode outside the workpiece passage region, a cathode inside the workpiece passage region including a hollow region through which a mixed fluid of the plating solution and the object to be plated passes from below toward above, and a guidance unit that guides the mixed fluid to the workpiece passage region.

A washing cabinet for cleaning a part. The washing cabinet comprising: a sonication tank configured to contain a volume of liquid; at least one ultrasonic transducer configured to direct ultrasonic energy into the liquid in the sonication tank; a spray chamber disposed above the sonication tank; a spray system configured to direct liquid into the spray chamber; a part holder configured to support a part to be cleaned in the washing cabinet; a catch tray; an actuator system coupled to the part holder and the catch tray; the actuator system configured to move the part holder between an upper spray position in the spray chamber and a lower sonication position in the volume of liquid in the sonication tank; the actuator system configured to move the catch tray between a first tray position in the spray chamber and a second tray position; the catch tray positioned between the part holder and the sonication tank when the part holder is in the upper spray position and the catch tray is in the first tray position in the spray chamber; a liquid retaining tank separate from the sonication tank; and the catch tray having a tray outlet configured to direct liquid into the liquid retaining tank when the catch tray is in the first tray position in the spray chamber.

A cleaning system and method uses a tank holding a fluid detergent and an equipment assembly formed from a plurality of discrete components joined together. One or more ultrasound transducers remove one or more deposits on the equipment assembly by generating and propagating high frequency ultrasound waves into the fluid detergent while the equipment assembly is in contact with the fluid detergent.

A treatment device for single-stage treatment of a metal object to be treated by at least the steps of pickling and phosphating. The treatment device comprises at least the following: a treatment container for receiving the object to be treated and for receiving a flowable treatment substance; and a pump device for exchanging at least a fraction of the treatment substance. The treatment substance is flowable around at least one part of the object to be treated. The treatment substance comprises a phosphor- or phosphate-containing solution, in particular phosphoric acid. The phosphor- or phosphate-containing solution consists partly of water and partly of a reaction substance, and the reaction substance consists of phosphor or a phosphate and an additional treatment effect-improving substance. The proportion of the phosphor or phosphate in the reaction substance is at least 95%, and the reaction substance does not have a salt acid or sulfuric acid content.
