Glass, glass ceramic and ceramic articles with graded protective coatings of hardness and strength
The invention relates to glass, glass ceramics and ceramic articles with graded protective coatings of hardness and strength. An article comprising: a substrate having a glass, glass ceramic, or ceramic composition and comprising a major surface; and a protective film disposed on the main surface. The protective film includes a thickness greater than 1.5 microns and a maximum hardness greater than 15 GPa at a depth of 500 nanometers, measured on the film disposed on the substrate. Further, the protective film includes a metal oxynitride that is graded such that the oxygen concentration in the film varies by 1.3 atomic% or more. Further, the substrate includes an elastic modulus less than an elastic modulus of the film.
本申请涉及具有硬度和强度的分级保护涂层的玻璃、玻璃陶瓷和陶瓷制品。一种制品，其包括：基材，所述基材具有玻璃、玻璃陶瓷或陶瓷组成且包括主表面；以及布置在主表面上的保护膜。保护膜包括大于1.5微米的厚度和在500纳米深度处大于15GPa的最大硬度，这是在布置在基材上的膜上测得的。此外，保护膜包括金属氧氮化物，其是分级的，从而使得膜中的氧浓度变化1.3原子％或更大。此外，基材包括的弹性模量小于膜的弹性模量。
