Abstract: A process for reinforcing a glass-ceramic article, into which a maximum tension is introduced beneath the surface of the glass-ceramic, advantageously in proximity to said surface. The invention also relates to an enamel that can be used for this reinforcement, this enamel being formed from a glass frit having the following composition, the proportions being expressed as weight percentages: SiO2 50-66% MgO 3-8% Na2O ?7-15% K2O 0-3% Li2O ?0-12% CaO ?0-10% BaO ?0-15% Al2O3 0-3% ZrO2 0-3% ZnO 0-5% B2O3 0-8% the sum of the alkaline-earth metal oxides CaO+BaO moreover being between 8 and 15%, and the sum of the alkali metal oxides Na2O+K2O+Li2O moreover being between 7 and 20%. The reinforced glass-ceramics obtained by the process.

Abstract: Certain example embodiments relate to Ni-inclusive ternary alloy being provided as a barrier layer for protecting an IR reflecting layer comprising silver or the like. The provision of a barrier layer comprising nickel, chromium, and/or molybdenum and/or oxides thereof may improve corrosion resistance, as well as chemical and mechanical durability. In certain examples, more than one barrier layer may be used on at least one side of the layer comprising silver. In still further examples, a NixCryMoz-based layer may be used as the functional layer, rather than or in addition to as a barrier layer, in a coating.

Abstract: Example embodiments of this invention relate to a coated article including an infrared (IR) reflecting layer of a material such as silver or the like, for use in an insulating glass (IG) window unit for example. In certain example embodiments, the coating is a single-silver type coating, and includes an overcoat including an uppermost layer of or including silicon nitride and a layer of or including tin oxide immediately under and contacting the silicon nitride based overcoat. In certain example embodiments, the thicknesses of the silicon nitride based overcoat and the tin oxide based layer are balanced (e.g., substantially equal, or equal plus/minus about 10%). It has surprisingly been found that such balancing results in an improvement in thermal cycling performance and improved mechanical durability. In certain example embodiments, the coating may realize surprisingly good substantially neutral film side reflective coloration, and may achieve an improved visible transmission, SHGC ratio and low U-values.

Abstract: An insulating glass (IG) window unit includes first and second substrates, and a low-emissivity (low-E) coating supported by one of the substrates. The low-E coating has two silver based infrared (IR) reflecting layers and allows the IG window unit to realize an increased SHGC to U-value ratio, and an increased thickness ratio of an upper silver based layer of the coating to a bottom silver based layer of the coating. The low-E coating is designed to have a low film-side reflectance, so that for example when the low-E coating is used on surface number three of an IG window unit the IG window unit can realize reduced visible reflectance as viewed from the outside of the building on which the IG window unit is mounted or is to be mounted.
Abstract: This invention relates to a coated article including a low-emissivity (low-E) coating. In certain example embodiments, the low-E coating is provided on a substrate (e.g., glass substrate) and includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers) and a dielectric layer of or including a material such as silicon nitride. In certain example embodiments, the coated article has a low visible transmission (e.g., no greater than 50%, more preferably no greater than about 40%, and most preferably no greater than about 39%).

Abstract: A coating and associated method for coating is disclosed. The coating provides a hard, transparent, UV blocking coating for a substrate. A UV blocking layer is first deposited upon the substrate, and a hard coating is deposited above the UV blocking layer. A soft coating layer may be deposited between the UV blocking layer and the hard coating. The soft and hard coating layers may both have the general composition SiOxCy. the soft and hard coating layers may be deposited by a plasma vapor deposition process.

Abstract: Provided is low emissivity glass including a low emissivity layer containing electrically conductive metal; and a composite metal oxide formed on one or both sides of the low emissivity layer and expressed by a following chemical formula 1: TiCeOx??(1) wherein Ti is titanium element, Ce is cerium element, and Ox is oxide. Since the dielectric layer which serves as protecting low emissivity layer of low emissivity glass and reducing emissivity contains the composite metal oxide expressed by the above chemical formula 1, visible light transmissivity can be greatly increased with excellent low emissivity.
Abstract: Described are hybrid articles comprising at least one hard non-oxide or oxide ceramic component of at least 95% of theoretical density directly bonded to, and different from, a hard non-oxide or oxide ceramic composite component comprising a tribology enhancing component.

Abstract: Temperable and non-temperable coatings are provided which have similar optical characteristics. The non-temperable coating is placed on glass that is not to be tempered and provides certain optical characteristics. The temperable coating is placed on a glass substrate and the coated substrate is then tempered. After tempering, the coated tempered glass sheet and the coated non-tempered glass sheet have similar optical characteristics. Both coatings have a plurality of metal layers, with at least one of the metallic layers being a discontinuous layer with a primer layer over the discontinuous metal layer. For the non-temperable coating, the discontinuous metal layer has an effective thickness in the range of 1.5 nm to 1.7 nm. For the temperable coating, the discontinuous metal layer has an effective thickness in the range of 1.7 nm to 1.8 nm. The primer layer of the temperable coating is thinner than the primer layer of the non-temperable coating.
