DLC Standardization

DLC standardization activities

JNDF has been carrying out a project for the standardization of DLC (Diamond-Like Carbon) commissioned by Ministry of Economy, Trade and Industry of Japan (METI). The purposes of this project are as following.

  • (1) A simple evaluation method for DLC which is based on its optical properties is developed; a draft ISO standard concerning the evaluation method for the optical properties of DLC is proposed.
  • (2) A draft ISO standard concerning the evaluation method for the adhesive strength of DLC is proposed.
  • (3) Databases for the amorphous carbon films containing DLC are made; the framework of ISO standard related to DLC is created.
