Results and Discussion - Essay ExampleAfter leaving the substance in the test solution for some time, it is weighted to measure the extent of loss in its weight. It is considered to be the importive method of testing the materials characteristics. In this chapter, a lifelike representation of corrosion testing is given. The corrosion testing was performed with the solution of Nacl with the quantity of 0.9%. Ocp vs time A Pictorial Representation of OCP verses Time with skid and no-skid depiction. On x and y-axis, allocation of time and authority mV is given. 4.2 Tribocorrosion The second phase of experiment involves testing the tribocorrosion properties of materials. In the process of potentiostatic measurement, an application of a potential that is constant is applied on the sample with the measurements taken within a period of time. A curve is obtained as a result of this electrochemical process. hither the results of the experiment have been presented in graphical form and in the form of profiles. It has been shown that the effect is of two types in which one consisted of sliding and the another(prenominal)wise with no sliding. When sliding is done with OCP, it causes damage in the passive film. However, on current, sliding has the effect of increasing it at a significant level. It is important to mention that tribocorrosion is considered to be an invaluable area of research which needs further investigation by various researchers in future. The figure describe the test 1 in a graphical form where time versus potential mV is plotted at x and y-axis. The potential is shown to be increasing slightly with the time till the end. It can be seen from the figure given above that OCP as depicted in blue remains constant throughout except at starting and a burn down end signify at 8000 and reach 0.3. However, HE OCP as exhibited in red color reached at a higher point at 0.4 where other points are the same as OCP. The figure represents the testing of distill water in a graphical form. The graph shows distill water going at the point between 0.4 and 0.5 reaching at 7000. The water was shown to be increasing rapidly at the starting point and slightly decreased at the other points till end. The figure represents the test at -750mV with the comparison of HE at-750mV. It is clear from this graphical representation that at-750mV final point is 8000 with 0.5 at y-axis. However, HE at-750mV is at the point above 0.4 but lower than 0.5. In the figure given above, a comparison of at+ 500mV has been given with HE at +500mV in a graphical form. -500mV is at the point 0.3 ranging from 0 to 10000 x-axis. However, HE at+500mV is shown at the starting point of zero from where it started increasing. The rate of increase remained constant for a enchantment with a great decrease at the point of 10000. In this figure the load effect has been seen in forward direction and the results show slightly change levels of load. The graphs depicts that at the load 0.5 COF began to increase and gets stable with the passage of time. However, the other loads show the stable position of COF at various points. This figure is the representative of effect of load in forward direction and shows average COF to increase considerably with loads. However, it decreases after some time and in the end does not require dependence of a load. The graph represents the effect of load in reverse form in which
