Abstract:
A method of making a curved laminated vehicle windshield, the method comprising:providing first and second glass sheets; placing the first and second glass sheets in juxtaposed relation with one another and heat bending the sheets together; positioning an interlayer between the two heat bent glass sheets; heating the glass sheets with interlayer therebetween in order to laminate the first and second glass sheets to one another via at least the interlayer, thereby forming a curved laminate including a convex surface and a concave surface; ion beam milling the convex surface of the curved laminate in order to shave off or remove a portion of the first glass sheet thereby forming a milled convex glass surface of the curved laminate; ion beam depositing a diamond-like carbon (DLC) inclusive coating directly on the milled convex glass surface of the curved laminate using a non-focused ion beam so that the DLC inclusive coating contacts the glass of the milled convex glass surface, thereby forming a vehicle windshield having an outer or convex surface including a DLC inclusive coating thereon; and wherein said ion beam depositing is carried out so that a temperature of the curved laminate does not rise above 70 degrees C. during coating depositing on the milled convex glass surface.
