Pulsed plasma deposition of chromium oxide/chromium-cermet coatings
A novel radio frequency magnetron sputtering method for the deposition of composite films which consist of chromium oxide and chromium ~Cr2O3/Cr-cermet! is presented. As an extension to conventional reactive sputtering of a Cr target in an argon and oxygen atmosphere the oxygen flow into the process chamber is switched periodically on and off. This leads to an oscillating oxygen partial pressur...
متن کاملBistable memory effect in chromium oxide junctions
Magnetotransport properties of granular CrO2 /Cr2O3 films made of CrO2 crystals covered by 12 nm native insulating Cr2O3 are presented. Electrical properties of a limited number of grains measured in series and parallel (10 to 15 grains) reveal intergrain tunneling characteristics. At lowest temperatures, a well pronounced zero bias anomaly indicates that impurities in the junctions block the e...
متن کاملDimensionally Controlled Lithiation of Chromium Oxide
Oxide conversion reactions are an alternative approach for high capacity lithium ion batteries but are known to suffer from structural irreversibility associated with the phase separation and reconstitution of reduced metal species and Li2O. In particular, the morphology of the reduced metal species is thought to play a critical role in the electrochemical properties of a conversion material. H...
متن کاملInterfacial Microstructure of Chromium Oxide Coatings
Chromium oxide coatings are chemically inert, have high mechanical strength, hardness and good optical characteristics; therefore, they have been widely used in many applications including corrosion protection, wear resistance, electronics, and optics. Cr2O3 is well suited for wear resistance applications, as it is one of the hardest oxides with 29.5 GPa hardness. Several deposition techniques ...
متن کاملSynthesis of Chromium Oxide Nano Particles by Thermal Decomposition Method
Disclosed is a method of preparing pigmentary chromium oxide nano particles having 50 percent particle size less than about 100 nm. Preparation of nano chromium (III) oxide is investigated by thermal decomposition method. According to the disclosed method, a substantially dry solid composition of potassium dichromate and carbon active is heated in CO2 atmosphere to a temperature of about 60...
