Chemically strengthened and textured glass housing member

Chemically strengthened and textured glass housing member

A glass member for a housing of an electronic device may include an aluminosilicate glass substrate defining a first surface of the glass member, the first surface having a first surface roughness, a fused composite coating bonded to a portion of the aluminosilicate glass substrate and defining a se...

Zusammenfassung:A glass member for a housing of an electronic device may include an aluminosilicate glass substrate defining a first surface of the glass member, the first surface having a first surface roughness, a fused composite coating bonded to a portion of the aluminosilicate glass substrate and defining a second surface of the glass member, the second surface having a second surface roughness greater than the first surface roughness, a first ion-exchanged layer extending into the glass member and through the fused composite coating, and a second ion-exchanged layer extending into the glass member from the first surface. The fused composite coating may include an amorphous glass matrix and a crystalline material dispersed in the amorphous glass matrix.
