Method for forming a protective coating on glass
First Claim
1. A method for producing a coated glass or ceramic article having a surface formed from silicates, said surface being selected from the group consisting of a sandblasted glass, an artistic glass, a float glass, and a Pyrex glass product, said method comprising the steps of:
- contacting the uncoated glass or ceramic article in a gaseous atmosphere at a pressure of at least 700 Torr with a silane vapor and a gaseous carbon source for a sufficient time at a temperature of less than 35°
C. to form a coating on and in the glass or ceramic surface, wherein said coating comprises a silicon-carbide-containing layer having a thickness of at least 100 angstroms and containing 35 to 55 atom % carbon, between 15 and 30 atom % silicon, no more than 10 atom % elements other than silicon, oxygen, and carbon, and the remainder oxygen.

Abstract
A method for producing a coated glass or ceramic article having a surface formed primarily from silicates, comprising the steps of contacting the uncoated glass or ceramic article in a gaseous atmosphere at a pressure of at least 700 Tort with a silane and a carbon source for a sufficient time at a temperature of less than 35° C. to form a coating on and in the glass surface, wherein the coating comprises a silicon-carbide-containing layer having a thickness of at least 100 angstroms and containing 35 to 55 atom % carbon, between 15 and 30% silicon, no more than 10% elements other than silicon, oxygen, and carbon, and the remainder oxygen. Glass and ceramic surfaces having the indicated compositions are also part of the invention.

7. A method of coating an article with a substantially transparent surface coating, said method comprising steps of:
-
providing the article comprising a surface material selected from the group consisting of a sandblasted glass, an artistic glass, a float glass, a Pyrex glass product, and a ceramic material; and reacting a silane and a carbon source on said surface material to form a substantially transparent surface coating on said article; wherein said surface material is at a temperature ranging from about 1°
to about 35°
