1. A method for removing material from a component, comprising the steps of:
connecting the component as an anode;
connecting a single electrode as a cathode;
guiding the single electrode to the component such that a gap is defined between the electrode and the component;
forming a duct defined by at least a part of a surface of the component and a part of a surface of the electrode and including an inlet opening and an outlet opening defined by at least the component and the single electrode, wherein the inlet opening is disposed at a first distal end of the duct and the outlet opening is disposed at a second distal end of the duct, wherein the duct is further defined by two guide elements that each extend along an entire longitudinal length of the duct, wherein the guide elements are mounted on the single electrode such that when the gap is defined the duct is also simultaneously defined, where the formed duct has a box shape with a lower wall which is the part of the surface of the component, an upper wall which is the part of the surface of the single electrode, and side walls orthogonal to the lower wall and the upper wall which are the two guide elements, wherein the two guide elements, as the side walls, contact the single electrode and the component such that an electrolyte is circulatable through the formed duct around the component only at the part of the surface of the component that is the lower wall of the duct; and
continuously guiding the electrolyte through the duct from the inlet opening to the outlet opening during a removal of the material from the component.
2. The method according to claim 1, wherein the electrolyte is introduced into the inlet opening at a pressure of 2 to 50 bar.
3. The method according to claim 1, wherein the electrolyte is introduced into the inlet opening via a nozzle.
4. The method according to claim 1, wherein the component is an engine component made of nickel-based or titanium-based alloys.
5. The method according to claim 4, wherein the component is a blade.
6. The method according to claim 1, wherein the two guide elements are non-conductive.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An aspirator for generating crinis for a baldhead, comprising:
a smooth helmet 10 that has a certain size enough for covering a portion having no hairs in a human head;
a tube 11 that is attached at an inner edge portion of the helmet for being inflated by air;
a sealing packing 13 of which a surface contacting with a human skin is made of a smooth material such as silicon wherein said sealing packing 13 is attached to the tube 11;
a jaw strip 14 and a fixing ring 15 for fixing the helmet 10 to the head;
an air injection pump 12 that is attached to a front side of the helmet 10 and is connected with a hose for filling air into the tube 11;
an air hose 40 of which one end is connected with an air switch 50 and a vacuum pump 60, and the other end is connected with a connection means 20 for thereby making the interior of the helmet 10 a vacuum state; and
a filter 30 that is attached at an inner upper side of the helmet 10 for preventing the hairs from being sucked out during a vacuum sucking operation based on an operation of the vacuum pump 60 and has a plurality of small holes connected with the connection means 20, whereby the air hose 40 and the helmet 10 are integrally engaged using the connection means 20, so that a certain vacuum pressure is obtained in the interior of the aspirator during a vacuum absorption operation.
2. The aspirator of claim 1, wherein said helmet 10 is made of one material selected among transparent resin, plastic or engineering plastic so that a certain change of the head skin is visually checked during an aspiration therapy.
3. The aspirator of claim 1, wherein said filter 30 is made of one material selected among transparent resin, plastic or engineering plastic so that a certain change of the head skin is visually checked during an aspiration therapy.
4. The aspirator of claim 3, wherein a plurality of massage protrusions 31 are installed at an inner side of the filter 30 directly contacting with the head skin.
5. An aspirator for generating crinis for a baldhead characterized in that said aspirator of claim 1 is used as a device for generating crinis by enhancing a blood circulation at a portion having no hairs.
