Abstract

A coated glass article and methods for producing the same are provided herein. The coated glass article includes a glass body having a first surface and a second surface opposite the first surface, wherein the first surface is an exterior surface of the glass body, and a damage-resistant coating formed by atomic layer deposition, the damage-resistant coating being disposed on at least a portion of the first surface of the glass body.

First claim

What is claimed is:

1 . A method for forming a coated glass container having a damage-resistant coating, the method comprising:
applying a damage-resistant coating to a glass container by atomic layer deposition, wherein applying the damage-resistant coating comprises exposing the glass container to a metal precursor and at least one of a water precursor and an amine precursor.

2 . The method of claim 1 , wherein the metal precursor comprises a precursor selected from the group consisting of an aluminum precursor, a zirconium precursor, a zinc precursor, a silicon precursor and a titanium precursor.

3 . The method of claim 1 , wherein exposing the glass container to a metal precursor and at least one of a water precursor and an amine precursor comprises exposing the glass container in a reactor chamber.

4 . The method of claim 1 , wherein applying a damage-resistant coating to a glass container comprises applying the damage-resistant coating to substantially all of the external surface of the glass container.

5 . The method of claim 1 , wherein applying a damage-resistant coating to a glass container comprises applying the damage-resistant coating to a portion of the external surface of the glass container.

6 . The method of claim 1 , wherein exposing the glass container to a metal precursor and at least one of a water precursor and an amine precursor comprises exposing the glass container at a temperature of between about 100° C. and about 200° C.

7 . The method of claim 1 , wherein exposing the glass container to a metal precursor and at least one of a water precursor and an amine precursor comprises exposing the glass container at a pressure of between about 1 mbar and about 10 mbar.

8 . The method of claim 1 , wherein applying a damage-resistant coating comprises applying a plurality of layers of the damage-resistant coating in a layer-by-layer process, wherein each layer of the plurality of layers is deposited during an ALD-cycle.

9 . The method of claim 8 , wherein each layer of the plurality of layers of the damage-resistant coating comprises a thickness of between about 0.1 nm and about 5.0 nm.

10 . The method of claim 1 , wherein the coated glass container is selected from the group consisting of vials, ampoules, cartridges and syringe bodies.

11 . The method of claim 1 , wherein the glass container comprises an ion-exchangeable glass composition.

12 . The method of claim 1 , wherein the glass container comprises a Type 1B glass composition.
