摘要： Embodiments of a glass-based article including a first surface and a second surface opposing the first surface defining a thickness (t) of about 3 millimeters or less (e.g., about 1 millimeter or less), and a stress profile, wherein all points of the stress profile between a thickness range from about 0·t up to 0.3·t and from greater than about 0.7·t up to t, comprise a tangent with a slope having an absolute value greater than about 0.1 MPa/micrometer, are disclosed. In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0·t to about 0.3·t) and a maximum central tension in the range from about 80 MPa to about 100 MPa. In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a value at a point between the first surface and the second surface and increases from the value to the second surface. The concentration of the metal oxide may be about 0.05 mol % or greater or about 0.5 mol % or greater throughout the thickness. Methods for forming such glass-based articles are also disclosed.

摘要： An article that includes: a substrate having a glass, glass-ceramic or a ceramic composition and comprising a primary surface; and a protective film disposed on the primary surface. The protective film comprises a thickness of greater than 1.5 microns and a maximum hardness of greater than 15 GPa at a depth of 500 nanometers, as measured on the film disposed on the substrate. Further, the protective film comprises a metal oxynitride that is graded such that an oxygen concentration in the film varies by 1.3 or more atomic %. In addition, the substrate comprises an elastic modulus less than an elastic modulus of the film.

摘要： One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. The bridging of a crack from one of the film or the glass substrate into the other of the film or the glass substrate can be suppressed by inserting a nanoporous crack mitigating layer between the glass substrate and the film.

摘要： A glass element having a thickness from 25 μm to 125 μm, a first primary surface, a second primary surface, and a compressive stress region extending from the first primary surface to a first depth, the region defined by a compressive stress GI of at least about 100 MPa at the first primary surface. Further, the glass element has a stress profile such that it does not fail when it is subject to 200,000 cycles of bending to a target bend radius of from 1 mm to 20 mm, by the parallel plate method. Still further, the glass element has a puncture resistance of greater than about 1.5 kgf when the first primary surface of the glass element is loaded with a tungsten carbide ball having a diameter of 1.5 mm.

摘要： A coated article includes a substrate having a major surface, and an optical coating disposed on the major surface of the substrate. At least a portion of the optical coating includes a residual compressive stress of about 50 MPa or more. The coated article has strain-to-failure of about 0.5% or more as measured by a Ring-on-Ring Tensile Testing Procedure. The coated article has an average photopic transmission of about 80% or greater.
