Abstract:
This invention relates to a method of making a window (e. g. , vehicle windshield, architectural window, etc. ), and the resulting window product. At least one glass substrate of the window is ion beam treated and/or milled prior to application of a coating (e. g. , sputter coated coating) over the treated/milled substrate surface and/or prior to heat treatment. As a result, defects in the resulting window and/or haze may be reduced. The ion beam used in certain embodiments may be diffused. In certain embodiments, the ion beam treating and/or milling is carried out using a fluorine (F) inclusive gas(es) and/or argon/oxygen gas(es) at the ion source(s). In certain optional embodiments, F may be subimplanted into to treated/milled glass surface for the purpose of reducing Na migration to the glass surface during heat treatment or thereafter, thereby enabling corrosion and/or stains to be reduced for long periods of time.
