Method for coating an object
View Patent ↗A method for coating an object ( 1 ). The object ( 1 ) is positioned in contact with holding means and the coating ( 4 ) is applied in such a way that contact parts ( 3, 8, 10 ) of the holding means form part of the coating ( 4 ). Contact parts ( 3, 8, 10 ) are made from a material having corrosion properties being substantially identical to the corrosion properties of the coating material, preferably from the same material. Thereby the contact parts ( 3 ) can form a natural part of the resulting coating ( 4 ). The contact parts ( 3, 8, 10 ) may subsequently be detached from the holding means and remain attached to the object ( 1 ) as part of the coating ( 4 ). Provides a substantially full coating ( 4 ) to the object ( 1 ) in one coating step. Avoids or reduces problems relating to pinholes in coatings. Further an object ( 1 ) having a coating ( 4 ) which has been provided using the method.
1. A method for coating an object, the method comprising the steps of:
providing holding means for holding the object during coating, the holding means comprising one or more contact parts being in contact with the object during coating;
positioning the object in contact with the holding means by attaching the contact part(s) to the object so that the object is hanging from the holding means; and
providing a coating to the object and around the contact part(s) in such a way that the contact part(s) and the coating together cover the object;
wherein at least the contact part(s) of the holding means is/are manufactured from a material having corrosion properties being at least substantially identical to the corrosion properties of the coating material.
2. The method according to claim 1 , further comprising the step of:
detaching the coated object from the holding means in such a way that at least the contact part(s) subsequently form(s) part of the object , the contact part(s) thereby being detached from the rest of the holding means.
3. The method according to claim 1 , wherein at least the contact part(s) of the holding means is/are manufactured from the same material as the coating material.
4. The method according to claim 1 , wherein the contact part(s) of the holding means comprise(s) at least one wire.
5. The method according to claim 4 , wherein the step of positioning the object comprises drilling at least one hole in the object and positioning the wire(s) in said hole(s), and wherein the step of providing a coating comprises filling gaps between the wire(s) and inner walls of the hole(s) with the coating material.
6. The method according to claim 1 , wherein the contact part(s) of the holding means comprise(s) at least one spike being adapted to support a lower part of the object.
7. A coated object, comprising:
a holding means comprising one or more contact parts that are attached to the object, such that the object hangs from the holding means; and
a coating material covering the surface of the object and around the contact part(s) of the holding means such that the contact part(s) and the coating together cover the object;
wherein the contact part(s) of the holding means is/are manufactured from a material having corrosion properties substantially identical to the corrosion properties of the coating material.
8. The method according to claim 1 , wherein the step of positioning the object comprises soldering the contact part(s) of the holding means onto the object.
9. The method according to claim 1 , wherein the coating material is a metal or an alloy.
10. The method according to claim 9 , wherein the coating material is tantalum or an alloy of tantalum.
11. The method according to claim 1 , wherein the object is manufactured from one or more metals and/or one or more alloys.
12. The object according to claim 7 , wherein the object is adapted to be implanted into the body of a mammal.
13. The object according to claim 12 , wherein the object is or forms part of an artificial bone structure.
14. The object according to claim 12 , wherein the object is or forms part of an artificial tooth.
15. The object according to claim 7 , wherein the object is or forms part of a structure which is subject to a risk of corrosion.
16. The object according to claim 7 , wherein the object is or forms part of a structure which is subject to a risk of chemical contamination.
17. The method according to claim 1 , wherein the step of positioning the object comprises welding the contact part(s) of the holding means onto the object.
18. The method according to claim 1 , wherein the coating and the contact part(s) of the holding means together provide a full coating to the object without pinholes.
19. The method according to claim 1 , wherein the contact part(s) of the holding means are made from the same material as the coating.
20. The object according to claim 7 , wherein the coating and the contact part(s) of the holding means together provide a full coating to the object without pinholes.
