Abstract
A transparent article having improved abrasion resistance, and method of making the same, which comprises a body of transparent glassy siliceous material having a smooth continuous surface and a continuous film of chromium silicide sputter-coated on said continuous surface to a thickness of from about 200 to 1,000 A.
Claims5
An article of manufacture, a transparent glazing element comprising, a transparent sheet of glass having a smooth continuous surface, and a continuous abrasion resistant transparent reflective film of chromium silicide adhered to said smooth continuous surface, said chromium silicide film consisting essentially of chromium and silicon and being of a thickness of from about 200 to 1,000 Angstroms.
The method of making a transparent glazing element comprising, providing a transparent sheet of glass having a smooth continuous surface, and sputter-coating on said smooth continuous surface a continuous abrasion resistant transparent reflective film of chromium silicide consisting essentially of chromium and silicon and being of a thickness of from about 200 to 1,000 Angstroms.
In the method of making a transparent glazing element comprising a transparent sheet of glass having a smooth continuous surface and a continuous abrasion resistant reflective film adhered to said smooth continuous surface, the improvement which comprises providing a sputtering target of chromium silicide consisting essentially of chromium and silicon, and sputtering said chromium silicide from said target in a low-pressure atmosphere containing an inert gas onto said smooth continuous surface of the glass sheet to form a transparent film having a thickness of from about 200 to 1,000 Angstroms.
