Effect Of Hardness In Chemistry

Great Essays
In this study, the main object is to find out the hardness change due the carbonized and non-carbonized alloys in air cool or water quench’s hardness differences. And the result showed that the carbonized with in air cool samples to compare with the normal air cool without covered carbon powder were similar, but the one covered with carbon were increased the overall hardness than the one without. On the carbonized with water quench it showed the one covered with carbon can provided more hardness (twice or more) than the center and also the one without covered carbon.
Introduction:
Diffusion on a manufacturing industry is a process of increasing the harness of the metal itself usually is for the alloy that contain carbon, which usually a

And to show what is the actually effect of the carbonized and non-carbonized metal there is a graph to show the hardness between the carbonize furnace cool, water quench, and non-carbonize furnace cool, and water quench. From the result it showed that for the normal air cool no matter is carbonized or non-carbonized the hardness wouldn’t really change too much because of the temperature. However, on the water quick quench that it showed that the one with faster cooling with the carbonized alloy, the hardness will be increased twice or more to compare the center or the alloy itself. For the non-carbonized alloy, it showed that it has a higher hardness from the surface and its overall hardness were increase which the center of the hardness is also higher than the water quench. To have a further more calculation to find out the depth of the case hardening with the Fick’s 2nd law, it able to proof that the heat treatment and the cooling rate will actually effect to the hardness of the alloy. And here is the …show more content…
C_0 will be .26% and for the C_x the one with carbon powder surface because since there is a carbon covered, will be assumed is 6.67%wt of carbon assume is the maximum wt%, c_s will be unknown, and get x from the distance from the edge. Once all those data were input, the number will be showed as a graph. From the calculation it showed pretty clearly that the %of the carbon contain was close to the fact which is during the heat process with the carbon powder, most of the carbon powder will be diffuse into the alloy surface, but the further it goes the less carbon it can get it is because the heat wasn’t able to transfer evenly to every part of the metal. Which it lead to it the closer to the center of the metal, the less carbon contain it will have for the case hardening

    3) Contact Resistance The contact resistance of the anode to electrolyte and of the cathode to electrolyte is a component of the overall corrosion cell resistivity—the lower the contact resistance, the greater the corrosion current. As the contact resistance increases, the corrosion cell current will decrease. The decrease will be in relation to the sum of the total resistance of the circuit. That is, the resistance of the electrolyte plus the contact resistance. 4) Coating of the Structure Coating of the structure usually raises the contact resistance of the anode and therefore the cathode since most coatings have a high dielectric (non-conductive)…

    This leads to the definition of conclusions The activity coefficients of sulfur and aluminum will be calculated by using the interaction parameters (which is equal to fS = 0.71, fAl = 1.13), we can estimate the degree of desulphurization of the investigated melt. Equation (6) shown, that increasing temperature resists desulfurization process thermodynamically. However, increasing temperatures should have a positive effect on the kinetics of the process, for example by reducing the viscosity of the metal and slag, which improves transition of sulfides from metal to slag. The work assessed the influence of composition of slag mixture on the degree of desulphurization of the melt. On smooth experiences changed the relationship between the oxide of rare earth metals and the consumption of processed feldspar.…

    It was hypothesized that copper was to become hotter than water when the same heat energy is applied to both. However does not appear to be the case when observing the analyzed data. A possible explanation for this is when substances heat up, they begin to require more energy to continue heating because the space around the substance starts trying to equilibrate with it and cool it down, (http://www.tutorvista.com, 2015). Between copper calorimeter tests, there wasn’t enough time to wait for the copper calorimeter to cool. On the other hand, the water calorimeter had its water replaced between each test so its temperature was reset and ready to heat up quickly again.…

    Schematic of the physical model for the susceptibility of hot cracking during copper GTA welding. (I). Free crystalline region The actual line of S-L is lower compared with its corresponding theoretical line because of the influence of under cooling and low-melting eutectic. The α-Cu is crystallized from the liquids when the welding pool cools down the actual line of S-L. In this region, the size of α-Cu is smaller and the quantity of α-Cu is fewer.…

    Here the result shows the percentage change in the C.O.P when the air conditioning test rig run on the nanorefrigerant and nanolubricant instead of conventional refrigerant and oil. Addition of nanoparticle in the compressor oil is showing the better result as compare to the nanorefrigerant. The maximum C.O.P is showing at 1.50% mass concentration i.e. 19.44% & 23.19 % for nanorefrigerants and nanolubricant respectfully.…

    This oxide film is Al2O3 and Al(OH)3, in neutral solution, based on Pourbaix diagram [20]. The alloy 1 presents OCP value of about -1.30 V whereas that of Alloy 2 was -1.44 V, which are more negative than that of Al in the same medium. The presence of tin and gallium in aluminum matrix as alloying elements increases the adsorption of Cl- ions at the values of negative potential which leads to the alloy dissolution [10]. The surface morphologies of Al, Alloy 1 and Alloy 2 after immersion in 2 M NaCl solution for 1 h were obtained by scanning electron microscopy (SEM) (Fig. 3).…

    My hypothesis was,If the freezing point depends on the number of ions in a substance, then the chemical aluminum chloride will have the greatest impact on the freezing point because it has the maximum amount of ions. My hypothesis was not supported because, NaCl is the additive that had the greatest impact on the freezing point because the concentration of the solution has less water molecules than the water…

    Addition-ally, ABE29.5W0.5 produced a lower NOx and CO and also increased UHC, but showed de-creased NOx and CO emissions compared to ABE30 and pure gasoline. Another study done by the same authors [226] also evaluated the effect of water-containing ABE-gasoline blends (ABE30, ABE85, ABE29.5W0.5 and ABE29W1) on combustion, performance, and emission characteristics of SI engine. In addition, ABE29W1 was compared with gasoline under vari-ous equivalence ratios and engine loads. The results revealed that ABE29W1 generally had a higher engine torque (3.1–8.2%) and lower CO (9.8–35.1%), UHC (27.4–78.2%) and NOx (4.1–39.4%) than those of gasoline. Study has investagated by [227] that reported a comparative study of high-alcohol-content gasoline blends in SI engines.…
