Chapter 4- Results of the Experiment The results of the experiment has been given in this chapter in with graphical representation and pictures of the actual experiment that had been conducted for the evaluation of corrosion, tribological and properties of linked wear and tear of the Cr-Co alloy that is used in medical-based implants.
After 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 effective method of testing the material’s characteristics. In this chapter, a graphical 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 sliding and no-sliding depiction. On x and y-axis, allocation of time and potential 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. Here 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 other 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. ...
