Ultra-hard, Anti-scratch Sapphire Thin Film Technology

The cover glass of electronic devices and the metal surface of luxury products are prone the scratch. The sapphire coating can provide scratch-protection and the fabrication cost of this coating is low.

• The hardness value of the Sapphire coating is over 8 on the Mohs scale, which means it's harder than most of the commercial cover glasses.
• The sapphire thin film can be deposited on different substrates including glasses, metals, and plastics, by standard industrial deposition processes. The fabrication process can be conducted at room temperature.

• The sapphire coating provides enhancement to the substrates, making the substrates ultra-hard and scratch-resistant.
• This technology provides cost-effective, high-throughput capability in fabrication of ultra-hard protection film on different substrate materials.
