Abstract: A method of strengthening an alkali aluminoborosilicate glass. A compressive layer extending from a surface of the glass to a depth of layer is formed by exchanging larger metal cations for smaller metal cations present in the glass. In a second step, metal cations in the glass are exchanged for larger metal cations to a second depth in the glass that is less than the depth of layer and increase the compressive stress of the compressive layer. Formation of the compressive layer and replacement of cations with larger cations can be achieved by a two-step ion exchange process. An alkali aluminoborosilicate glass having a compressive layer and a crack indentation threshold of at least 3000 gf is also provided.

Abstract: A scratch resistant alkali aluminoborosilicate glass. The glass is chemically strengthened and has a surface layer that is rich in silica with respect to the remainder of the glass article. The chemically strengthened glass is then treated with an aqueous solution of a mineral acid other than hydrofluoric acid, such as, for example, HCl, HNO3, H2SO4, or the like, to selective leach elements from the glass and leave behind a silica-rich surface layer. The silica-rich surface layer improves the Knoop scratch threshold of the ion exchanged glass compared to ion exchanged glass that are not treated with the acid solution as well as the post-scratch retained strength of the glass.
