Abstract

The invention provides a treatment plate ( 10 ) for a garment treatment appliance ( 100 ), the treatment plate ( 10 ) having a contact surface ( 13 ) that in use slides on a garment ( 200 ) being treated, the contact surface ( 13 ) comprising a coating ( 20 ) comprising a metal oxide coating ( 21 ), the metal oxide coating ( 21 ) comprising: —first metal ions selected from the group consisting of titanium (Ti), zirconium (Zr), hafnium (Hf), scandium (Sc), and yttrium (Y); and—second metal ions selected from the group consisting of cerium (Ce), manganese (Mn), and cobalt (Co). This invention provides a favorable gliding behavior.

First claim

second metal ions are cerium (Ce) ions, wherein the coating comprises a multi-layer coating comprising at least one layer selected from the group consisting of a metal layer, an enamel, an organic polymer comprising layer, an organo silicate comprising layer, a silicate comprising layer, and comprising said metal oxide coating as outer layer.

2. The treatment plate according to claim 1 , wherein the first metal ions are selected from the group consisting of titanium (Ti) and zirconium (Zr).

3. The treatment plate according to claim 1 , wherein the first metal ions are zirconium (Zr) ions.

4. The treatment plate according to claim 1 , wherein the metal oxide coating comprises a ratio of second metal ions to first metal ions of at maximum 2.

5. The treatment plate according to claim 1 , wherein the metal oxide coating has a layer thickness selected from the range of 50 nanometers 5 micrometers.

6. The treatment plate according to claim 1 , wherein the metal oxide coating is a sol-gel metal oxide coating.

7. The treatment plate according to claim 1 , wherein the metal oxide coating has a sheet resistance equal to or lower than 1.10 10 Ω/square.

8. A garment treatment appliance comprising a treatment plate as claimed in claim 1 , wherein the garment treatment appliance is selected from the group of appliances consisting of an iron, a steam iron, and a steamer.

9. A treatment plate for a garment treatment appliance, the treatment plate having a contact surface that in use slides on a garment being treated, the contact surface comprising a coating comprising a metal oxide coating, the metal oxide coating comprising:
first metal ions selected from the group consisting of titanium (Ti), zirconium (Zr), hafnium (Hf), scandium (Sc), and yttrium (Y); and
second metal ions selected from the group consisting of cerium (Ce), manganese (Mn), and cobalt (Co), wherein the coating comprises a multi-layer coating comprising at least one layer selected from the group consisting of a metal layer, an enamel, an organic polymer comprising layer, an organo silicate comprising layer, a silicate comprising layer, and comprising said metal oxide coating as outer layer,
wherein the metal oxide coating comprises a ratio of second metal ions to first metal ions of at least 0.015.

10. The treatment plate according to claim 9 , wherein the second metal ions are selected from the group consisting of cerium (Ce) and manganese (Mn).

11. The treatment plate according to claim 9 , wherein the first metal ions are selected from the group consisting of titanium (Ti) and zirconium (Zr).

12. The treatment plate according to claim 9 , wherein the metal oxide coating comprises a ratio of second metal ions to first metal ions of at maximum 2.

13. The treatment plate according to claim 9 , wherein the metal oxide coating has a layer thickness selected from the range of 50 nanometers 5 micrometers.

14. The treatment plate according to claim 9 , wherein the metal oxide coating is a sol-gel metal oxide coating.

15. A treatment plate for a garment treatment appliance, the treatment plate having a contact surface that in use slides on a garment being treated, the contact surface comprising a coating comprising a metal oxide coating, the metal oxide coating comprising:
first metal ions selected from the group consisting of titanium (Ti), zirconium (Zr), hafnium (Hf), scandium (Sc), and yttrium (Y); and
second metal ions selected from the group consisting of cerium (Ce), manganese (Mn), and cobalt (Co), wherein the coating comprises a multi-layer coating comprising at least one layer selected from the group consisting of a metal layer, an enamel, an organic polymer comprising layer, an organo silicate comprising layer, a silicate comprising layer, and comprising said metal oxide coating as outer layer,
wherein the metal oxide coating comprises a ratio of second metal ions to first metal ions of at least 0.075.

16. The treatment plate according to claim 15 , wherein the first metal ions are selected from the group consisting of titanium (Ti) and zirconium (Zr).

17. The treatment plate according to claim 15 , wherein the metal oxide coating comprises a ratio of second metal ions to first metal ions of at maximum 2.

18. The treatment plate according to claim 15 , wherein the metal oxide coating has a layer thickness selected from the range of 50 nanometers-5 micrometers.

19. The treatment plate according to claim 15 , wherein the metal oxide coating is a sol-gel metal oxide coating.

20. A method of providing a treatment plate for a garment treatment appliance, the treatment plate having a contact surface that in use slides on a garment being treated, the method comprising the step of providing on at least part of the contact surface a metal oxide coating, wherein the metal oxide coating comprises:
