Superhard metallic coatings
Original language description
The letter reports on the surface hardening of bulk soft metal materials by protective coatings made of the same metal as bulk but with up to 6 times higher hardness than that of the bulk material. This surface hardening is demonstrated by covering of the Ti substrate with a low hardness Hbulk ≈ 5 GPa by a 1200 nm thick Ti coating with a high hardness Hcoating ≈ 30 GPa. The protective hard Ti coatings were sputtered by a new sputtering technology based on extremely high pressures (≥ 1000 GPa), high temperatures exceeding the melting temperature Tm of the coating material and extremely high cooling rate of the created coating (≥ 10^10 K/s). The principle of this technology realized at an atomic level is described in detail.
