A method for chemical processing an internal cavity of an additive manufactured (AM) metal workpiece is disclosed in which a connector is provided in fluid connection with the internal cavity and a chemical polishing solution is flowed through the connector and the internal cavity to process the internal cavity to a desired finish.

Chemical processing of additive manufactured workpieces

A highly reactive conversion coating chemistry is used during CAVF processing of high hardness steel alloys such as AMS 6509 and AMS 6517 steel alloys. This chemistry produces a hard, thin, black conversion coating that is not fully rubbed off by the media during the CAVF process. Distressed material regions on the surface of the alloys are not susceptible to forming the conversion coating and remain white. Visual inspection for the presence of such regions is facilitated.

A wind-turbine gearbox system includes an input gear stage having mating gear surfaces finished to a surface roughness of less than 0.25 micron and at least one bearing supporting the input gear stage. A lubrication circuit is arranged to deliver lubricant to the input gear stage and the bearing during operation of the wind-turbine and includes an inline filter for removal of particles of less than 2 micron from the lubricant prior to delivery. A lubricant for use in the system may have a relatively low viscosity compared to conventional wind turbine gearbox lubricants.

A method for finishing a surface of a metal component is carried out in a receptacle containing a quantity of non-abrasive media. The component is at least partially immersed in the media and a quantity of active finishing chemistry is supplied. The chemistry forms a relatively soft conversion coating on the surface. By inducing high energy relative movement between the surface and the media the coating can be continuously removed. The method may be carried out in a drag finishing machine.

High throughput finishing of metal components

A fixture is provided for retaining a metal workpiece for contact by finishing media during operation of a media based finishing operation. The fixture comprises a body and a magnet for retaining the workpiece in contact with the body. By use of super-magnetic materials a significant holding force may be achieved.

Refurbishing used or damaged engineering components is performed using a subtractive surface engineering process to remove material from worn or damaged critical surfaces. The method involves initially performing the process on the component to remove a first quantity of material from the surfaces, inspecting the surface of the component to determine the extent of damage and subsequently further performing the process to remove a further quantity of material if necessary.

Method for inspecting and refurbishing engineering components

The invention is an improvement in the metal finishing processes disclosed in U.S. Pat. No. 4,818,333. The improvement arises in the use of nonabrasive media, such as stainless steel or plastic, in combination with chemicals that are reactive to the metal surface processed. The invention also includes metal articles finished using this process.
