Laser-induced structure transition of diamond-like carbon coated on cemented carbide and formation of reduced graphene oxide

Autor: Eslam Abubakr, Jagdish Narayan, Mohamed Egiza, Ariful Haque, Abdelrahman Zkria, Koki Murasawa, Tsuyoshi Yoshitake

Publikováno v: MRS Communications. 9:910-915

We report on the structural evolution of diamond-like carbon (DLC) films by the nanosecond pulsed laser annealing process. DLC film is coated on cemented carbide (WC-Co) by cathodic arc ion plating, which is then annealed by ArF laser (193 nm, 20 ns)

Negative bias effects on deposition and mechanical properties of ultrananocrystalline diamond/amorphous carbon composite films deposited on cemented carbide substrates by coaxial arc plasma

Autor: Ali M. Ali, Mohamed Egiza, Yasuo Fukui, Hidenobu Gonda, Masatoshi Sakurai, Koki Murasawa, Tsuyoshi Yoshitake

Publikováno v: Diamond and Related Materials. 96:67-73

Ultrananocrystalline diamond/amorphous carbon composite (UNCD/a-C) films were deposited on negatively biased cemented carbide (WC-Co) substrates by coaxial arc plasma deposition. The deposition rate is increased to be 0.9 nm/s, which is approximately
