Decorative Titanium Nitride Colored Coatings on Bell-Metal by Reactive Cylindrical Magnetron Sputtering

The transition metal nitrides like titanium nitride exhibit very interesting color variation properties depending on the different plasma deposition conditions using cylindrical magnetron sputtering method. It is found in this deposition study that nitrogen partial pressure in the reactive gas discharge environment plays a significant role on the color variation of the film coatings on bell-met...

Decorative Portrats by Leonard Limousin

concentrate our attention upon the work of the little-known or even anonymous masters and endeavor to delineate the outlines of a "style" belonging not only to an individual but to a generation and a country. Particular problems in the decorative arts can in this way lead to an understanding of the mind and taste of a bygone age that is quite unexpected. Hence it is that such studies in the hig...

Coating Technology: Evaporation Vs Sputtering

Surface Morphology Evolution of GaAs by Low Energy Ion Sputtering

Low energy Ar ion sputtering, typically below 1,200 eV, of GaAs at normal beam incident angle is investigated. Surface morphology development with respect to varying energy is analyzed and discussed. Dot-like patterns in the nanometer scale are obtained above 600 eV. As the energy approaches upper eV range regular dots have evolved. The energy dependent dot evolution is evaluated based on solut...

Mass fractionation of the lunar surface by solar wind sputtering

The sputtering of the lunar surface by the solar wind is examined as a possible mechanism of mass fractionation. Simple arguments based on current theories of sputtering and the ballistics of the sputtered atoms suggest that most ejected atoms will have sufficiently high energy to escape lunar gravity. However, the fraction of atoms which falls back to the surface is enriched in the heavier ato...
