Synopsis This laboratory report gives an outline of the experiment which was carried out in order to measure the density of water at different temperatures via two different methods. The lab consisted of two parts. In the first part the density of water was measured by hydrometer. At first the density of water at room temperature was measured. In the next steps the density of water between 30-40 °C, 40-50 °C and 50-60 °C was measured.
Argon of 99.999% purity was used as shielding gas. The electrode gap was measured for each new weld prior to welding to ensure that the welding was performed under the same operating conditions. During the welding no consumables were added to the weld pool. A-TIG welding was carried out using fully automated process set-up in flat (PA/1G) position. Arc length L (Distance from the tip of the tungsten to the workpiece) was kept 2-3 mm.
Powder X-Ray Diffraction (XRD) is a rapid analytical technique primarily used for a crystalline material of phase purity and can provide information on unit cell dimensions. The analyzed is bulk composite material is, homogenized, and these particles used to be x-ray diffraction. Max von Laue, in 1912, discovered that crystalline material formation three-dimensional diffraction gratings for X-ray exposed similar to the spacing of planes in a crystal lattice. X-ray diffraction is now a common technique for the study of crystal structures and atomic spacing. Principle Monochoramatic X-ray is exposed crystalline sample and due to occur constructive interference of X-ray diffraction Patten.
They tested how the temperature would affect the rate of reaction. This was observed by the amount of time it took for the solution to change colors. For many chemical reactions there is an optimum temperature at which the chemicals will react with each other. As was found in their experiment, the temperature affected the rate of reaction. (Deoudes, 2010).
Using properties of both phases titanium alloys can achieve outstanding properties combinations of a high specific strength, high ductility, high creep resistance and high fatigue strength as well as high corrosion resistance. The methods used can be summarized under the term of thermo-mechanical-processing and may include forging, hot- and cold-rolling as well as several thermal treatments. 1.1.5. Titanium alloys Structural titanium alloys are often duplex alloys, containing the hcp α-phase and the bcc β-phase. In pure titanium the α-phase is stable below the allotropic transition temperatures Tβ =1155K while the β-phase is stable above Tβ, as shown in figure 1.
3 represents the TEM (CENTRA 100, Zeiss) images of ZP and ZPFe. The TEM images of ZPFe, Fig 3a and 3b (different magnification), show that the ZPFe retains the original morphology of the ZP, and a size of ~ 150 nm with clear crystal habit was observed. They show nanoparticles, which are on the smooth surface of the ZP with different sizes. The observable existence of metallic crystal nanoparticle indicates that agglomeration of iron deposited on the surface of the ZP. Almost the same observations were reported for zinc and cerium zirconium phosphate earlier [34,
Titanium is soluble in concentrated acids and it is able to rust. However, Phosphorus is soluble in Phosphorus Disulfide and is not able to rust. Not only do they differ at these properties, but they also have different atomic radii, electronegativity, and electron configuration. On one hand, Titanium’s atomic radius, or the size of its atom is 215 pm. Its electronegativity, or the “... measure of the tendency of an atom to attract a bonding pair of electrons,” (Clark Jim, 2013), is 1.54.
Stainless steel is an inoxydable which means it can’t be readily oxidized (incapable of rusting). Stainless steel is notable because of its good corrosion resistance. Increase in Chromium content increases the corrosion resistance in stainless steels. Stainless steels are differing from carbon steels because of chromium content present in it. When compared with stainless steel, carbon steels are readily rusted when reveal to the combination of moisture and air.
Titanium Dioxide Titanium dioxide (TiO2) is one of the most common chemicals being produced worldwide as it is being used as basic material in everyday living. It is a white powdered chemical typically utilized by the manufacturers of cosmetics, paper, sunscreen, food products, and many others that are included in the variety of industrial and consumer products (ChemicalSafetyFacts.org, n.d.). Knowing that it is an odorless, white-powdered chemical, it gives clarity to a certain product where it has been added. It can also maintain the color of the product and reflect the ultraviolet (UV) light which is why it can also be found in sunscreen products (Mercola, 2016). Titanium dioxide, also called as “titania”, exists in two distinct forms—anatase
{Titanium rings are currently very popular and have become a phenomenon and they are widely available in market and people love them because they provide properties that are unique because they are corrosion resistant, lightweight and also biocompatible.|The rings are very popular and have become a phenomenon and they are widely available in market and people love them because they provide properties that are unique because they are corrosion resistant, lightweight and also biocompatible.|They are widely available in market and people love them because they provide properties that are unique because they are corrosion resistant, lightweight and also
