Abstract

A wear resistant coating may comprise an amorphous metal comprising at least one refractory metal, at least two elements selected from periods 4, 5, 6, 9, and 10, and a metalloid. An amorphous metal may comprise at least one refractory metal, at least two elements selected from periods 4, 5, 6, 9, and 10, and a metalloid. A coating may comprise at least one refractory metal, at least two elements selected from periods 4, 5, 6, 9, and 10, and silicon. In some examples, the amorphous metal is TaWSi. In one example, the refractory metals may comprise Niobium, Molybdenum, Tantalum, Tungsten, Rhenium, or combinations thereof.

First claim

What is claimed is:

1. An apparatus comprising:
a wear resistant coating that coats a surface of the apparatus, the wear resistant coating including an amorphous metal comprising:
tantalum;
at least five elements selected from groups 4, 5, 6, 9, and 10 of the Periodic Table; and
at least one metalloid.

2. The apparatus of claim 1 , in which the at least one metalloid is Silicon (Si).

3. The apparatus of claim 1 , the apparatus further including a printhead, in which the wear resistant coating coats a chamber wall of a firing chamber in the printhead.

4. The apparatus of claim 1 , in which the amorphous metal comprises Tantalum (Ta), Tungsten (W), Silicon (Si), and at least three additional elements selected from groups 4, 5, 6, 9, and 10 of the Periodic Table.

5. The wear resistant coating of claim 1 , wherein the amorphous metal includes Molybdenum (Mo).

6. The wear resistant coating of claim 1 , wherein the amorphous metal includes Rhenium (Re).

7. An amorphous metal comprising tantalum, at least five elements selected from groups 4, 5, 6, 9, and 10 of the Periodic Table, and a metalloid.

8. The amorphous metal of claim 7 , in which the metalloid is Silicon (Si).

9. The amorphous metal of claim 7 , in which the number of elements selected from the groups 4, 5, 6, 9, and 10 of the Periodic Table is six.

10. The amorphous metal of claim 7 , comprising Tantalum (Ta), Tungsten (W), Silicon (Si), and at least three additional elements selected from the groups 4, 5, 6, 9, and 10 of the Periodic Table.

11. The amorphous metal of claim 7 , wherein the amorphous metal is a coating that coats a chamber wall of a firing chamber in a printer head, the metal comprising Tantalum (Ta), Tungsten (W), Silicon (Si), and at least three additional elements selected from the groups 4, 5, 6, 9, and 10 of the Periodic Table.

12. A coating comprising:
tantalum;
at least five elements selected from groups 4, 5, 6, 9, and 10 of the Periodic Table; and
silicon (Si).

13. The coating of claim 12 , wherein the coating comprises Tantalum (Ta), Tungsten (W), the Si, and at least three additional elements selected from the groups 4, 5, 6, 9, and 10 of the Periodic Table or combinations thereof.

14. The coating of claim 12 , wherein the coating comprises Niobium (Nb).

15. The coating of claim 12 , wherein the coating coats a chamber wall of a firing chamber in a printhead.

16. The coating of claim 12 , wherein the coating is free of grain boundaries.
