Results And Discussion On Weight Loss - 1734 Words

3 Results And Discussion 3.1 Wear Test Figure 4 shows the results of loss in weight for the samples as a function with the applied load. It has been found that the wear behavior of unreinforced alloy is higher compared with the composites. This behavior back to the hard ceramic material protects the surface from the severe contact [30–32]. The results given in figure 5 show that the weight loss decreases as the percentage of the nano SiC particles increases from 0.5% to 4.5%. This could be occurred because the ceramic material on the composite surface protects the matrix from severe contact. Figure 4 reveals also, that when the applied load increases, the wear rate of all investigated samples increases. Conditions of the severe wear were clearly seen from the rate of weight loss. The recognized pattern is steady with that perceived by Alpas and Zhang [33] they propose the wear rate increment bit by bit with the connected load in the gentle wear area. Then again, at a discriminating load that relies upon sliding speed, the wear rate suddenly increments reflect the condition termed serious wear. From figure 6 we can see that the composites weight loss is less than that of matrix alloy. The obtained weight loss results show that no single, unique wear mechanism operates over the wide range of the used weight (0- 4.5%). Rather, there are several mechanisms while the change in their relative importance as both the weight % of nano ceramic particles was varied and theShow MoreRelatedThe Health Belief Model Of The United States1367 Words   |  6 Pageswhich the individual believes that the consequences of overweight or obesity applies to them personally (Sharafkhani, et al. 30). For example, if the individual believes that they are unlikely to become diabetic or to develop high blood pressure as a result of being overweight or obese, the perceived susceptibility is low. If, however, the individual has several family members who have been diagnosed with hypertension or diabetes, they would be more inclined to believe that they have a high susceptibilityRead MoreDiffusion Of Dye Through Agar Gel Essay1672 Words   |  7 Pagesrelationship of molecular weight and that rate of diffusion through a membrane. Hypothesis of this experiment is that the fluid with higher molecular weight will diffuse at a slower rate and distance. METHODS AND MATERIALS: DIFFUSION OF DYE THROUGH AGAR GEL In order to assimilate diffusion through a permeable membrane potassium permanganate and methylene blue were used in experiment. The objective was to compare the rates at which the liquid compound of different molecular weight diffused through agarRead MoreBio. Lab.
