Disclosed herein are systems and methods for polishing internal surfaces of apertures in semiconductor processing chamber components. A method includes providing a ceramic article having at least one aperture, the ceramic article being a component for a semiconductor processing chamber. The method further includes polishing the at least one aperture based on flowing an abrasive media through the at least one aperture of the ceramic article, the abrasive media including a polymer base and a plurality of abrasive particles.

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.

Vibratory finishing apparatus comprising: a receptacle to receive media; a first fixture to: support an object within the receptacle; and move the object relative to the receptacle in at least a first direction; and a first guide to move relative to the receptacle to direct movement of the media within the receptacle to a predetermined part of the object.

A method for smoothing and polishing metals via ion transport by free solid bodies comprises connecting a part to be treated to a positive pole (anode) of a current generator and subjecting the part to friction with a set of particles comprising electrically conductive free solid bodies charged with negative electrical charge in a gaseous environment.

A method of treating an articular surface of a metal orthopedic implant includes polishing the surface, blasting the surface with a blast media after the first polishing step and polishing the blasted surface of the metal orthopedic implant after the blasting step. The blasting step roughens the surface to create a surface skew R.sub.sk/S.sub.sk defined by peaks and valleys. The second polishing step reduces the surface skew to a negative skew R.sub.sk/S.sub.sk and produces an average roughness R.sub.a/S.sub.a that is acceptable. Lubrication at the interface of the treated articular surface and the corresponding bearing articular surface is improved, thereby improving wear resistance. Both polishing steps may be performed by drag finishing the surface through an abrasive media.

The present subject matter relates to a method and an apparatus in the form of a machine system (1200) for machining a component (100) with an internal passage (115). In an aspect, the method comprises periodically injecting 5 abrasive slurry back and forth through the internal passage (115) at a pressure ranging from about 25 bar to about 35 bar. The abrasive slurry comprises a mixture of abrasive particles having a size in the range of about 40 m to about 60 m, and a slurry medium. The volume fraction of the abrasive particles in the slurry medium is about 40% to about 50%. Further, the injection of the abrasive 10 slurry is performed for a predefined number of process cycles at predetermined time versus pressure changes to obtain the component having a final average surface roughness of less than about 3.0 m.
