光学およびディスプレイ用の耐傷性コーティングにおける炭化ホウ素
Boron carbide delivers Vickers hardness of 2,900–3,580 HV combined with 85–92% visible transmittance, making it a technically superior choice over DLC and TiN for scratch-resistant coatings on optical elements and display glass. This article covers deposition methods, adhesion interlayer design, powder purity specifications, and the standardised test protocols that govern acceptance in optical and display supply chains.
