Actualities in the Cadastral Identification and the Measurement of Real Estate Property

This paper aims at presenting the current assessment methodology employed in the field of real estate, according to law. Within a correct evaluation of real estate properties, three sides of cadastral survey are taken into consideration, namely, the technical, the economic and the judicial side, in order to accurately reflect the information needed for this process. The case study presented refers to the analysis and evaluation of land in Galati County, based on the specific characteristics of real estate

Characterization of Sintered Hardmetals Coated with TiC

This paper presents the realization of TiC thin films by CVD method. The thin layers of TiC thicknesses were 8 and 10 μm, their thickness increasing with time, keeping the temperature. Diffractometer analysis certifies that this thin layer of TiC is homogeneous and unscratched. Microhardness of thin layers of TiC is HV0,05 = 30000 MPa compared to WC (carbide substrate of the component) that has a microhardness HV0,05 = 17000MPa

The molybdenum particles having particle sizes of 3 μm, respective 7 μm have been used as a complementary phase. The optimal conditions for codeposition were determined, the structure and chemical composition of the obtained coatings were presented and the coating characteristics were tested

Study And Researche Regarding Binaring Sistem With Tiobis - β – Naftol

This paper presents the results for contribution of determining the manganese from waters and steel. Manganese, due to its properties, cannot be found but in acid waters and usually associated with iron. In small amounts, the manganese is a necessary nutrient above all as activator of certain enzymes. In large amounts, though, coming from contaminated waters , the manganese is noxious and may cause brain damage l. It is considered that drinking water should not contain more than 0,1 ppm manganese. From the studies carried out , the tiobis-β-naftolul dissolved in etilic alcohol or isobutilic alcohol may be used to determine the Mn (II) ion , under certain conditions as described in the paper. To determine manganese (II) in water, a photometric extraction method has been developed. The method is new, useful and accurate and enables determining Mn in surface, underground and fishery waters

Structure-Property Correlation of Composite Materials Based on Cu-Mo Obtained by PVD Method

The paper describes reviews referring to determination of working parameters of the development processes of composites in copper matrix, by vapour-phase deposition method. The molybdenum was used as complementary phase. Structural characterization of coatings developed by optical microscopy and electronic scanning and effects of surface structure on their characteristics were presented. The specificity of the technology for obtaining Cu-Mo composites is a condition to formation a special laminated structure. The mechanical characteristics of the condensate depending on the amount of molibden. An important role in forming the structure and characteristics is played by the defects which were formed in the condensate during the transfer in the liquid phase as drops. Electrochemical tests have shown that the corrosion resistance of the composites obtained by PVD method is higher than pure copper

Structure and Corrosive Firmness of Composition Materials on the Basis of Copper and Molybdenum Got Method Electron-Beam Technology

The article describe the study of corrosive firmness of composition materials on the basis of copper, obtained by EB-PVD method. Corrosive firmness of condensates was explored by gravimetric method. The especially decreasing of the corrosive stability is definite during concentration of molybdenum about 12 %. Chemical composition of condensates showed that in the stationary terms of receipt of materials, their chemical composition is heterogeneous on a thickness. The structure of condensate has the expressly expressed macro-laminated character, the size of layers hesitates from a few ten microns of the to several hundred

Pregled tehnika recikliranja litij-ionskih baterija

This paper presents a literature review on the processing of used lithium-ion batteries in both industry and research. On an industrial scale, lithium-ion batteries are primarily processed through pyrometallurgical methods, leading to incomplete utilisation of lithium cells. On the other hand, the hydrometallurgical route of recycling lithium-ion batteries poses challenges, such as large-scale discharging or inert gas pretreatment, largely due to explosion hazards. Modern methods of lithium-ion battery recycling are oriented toward refining the leach liquor through solvent extraction methods using D2EHPA and Cyanex 272, to recover Co, Mn, and Ni. The final Li product is obtained through Na2CO3 precipitation.Ovaj rad predstavlja pregled literature o obradi rabljenih litij-ionskih baterija u industriji i istraživanju. U industrijskoj razini, litij-ionske baterije ponajprije se obrađuju pirometalurškim metodama, što dovodi do nepotpunog iskorištenja litijevih ćelija. S druge strane, hidrometalurški put recikliranja litij-ionskih baterija predstavlja izazove kao što su veliko pražnjenje ili predobrada inertnim plinom, uglavnom zbog opasnosti od eksplozije. Suvremene metode recikliranja litij-ionskih baterija usmjerene su na rafiniranje tekućine za ispiranje metodama ekstrakcije pomoću D2EHPA i Cyanex 272, da bi se dobili Co, Mn i Ni. Konačni produkt, Li, dobiva se taloženjem s Na2CO3

Corrosion Resistance in Neutral Saline Fog of the Composites Cu-Mo Obtained by PVD Method

The basic materials used for electrical contacts, which may be available economically, are the Cu-Mo based composites obtained by the method of electron flow at high temperatures under vacuum. Cu-Mo (12% max. Mo) composite materials are produced by simultaneous evaporation from separate Cu and Mo crucibles with subsequent condensation of the vapor flow on an OL-37 steel layer of 15 to 20 mm thickness and 800 mm diameter. The surface of the disk-support on which condensation of the vapor flow takes place was machined until a roughness of Ra =0.63 was obtained. Analysis of chemical composition and structure of composites based on copper and molybdenum content allowed determination of the variation of these elements from layer to layer (of up to 20-25% to 4-5 mas.) and the distribution gradient of these elements in the layers. The Cu-Mo composites produced by PVD method were introduced in the room and tested in neutral saline fog exposure time of 100h. Cu-Mo composites, obtained by PVD method, have a fairly good corrosion resistance, at Mo concentrations ranging from 8% to 12 % of the surface do not present oxides and the concentrations of Mo between 1,2 to 6% area are covered with oxide

On the Corrosion Resistance of Cu – Mo Composite Materials obtained by PVD Method

The Cu – Mo composite materials have been obtained by electron flow vaporizing followed by vapor –phase condensing. Researches have shown that corrosion resistance in wet environment varies with the content of molybdenum, working conditions and composition of the corrosion medium. The corrosion resistance of the composites has been studied by gravimetric method
