1Corrosion of MetalsAbstractDuring the experiment, the team learned how to measure the corrosion rate of twodifferent metals and to show the effectiveness of the use of inhibitors to protect metals fromcorrosion. In order to conduct a successful experiment, the team had to conduct a metallographicobservation. After grinding and polishing, the team made sure that the samples were ready fortesting by analyzing the samples through a microscope. Next, the team created the saltwatersolution and the antifreeze solution. Once the solutions were ready, the team was able to test bothspecimens in the antifreeze and saltwater solutions for fifteen minutes. Throughout theexperiment, the team realized that the samples that were tested in the solution without theinhibitor had a higher corrosion rate in comparison to the samples that had the inhibitor. Overall,the team saw that the brass specimen was more resistant to corrosion in comparison to the steelspecimen. The results can be seen in Table 2.IntroductionWhen an engineer is choosing a metal for a project, it is important to see what metals canwithstand the climate and region of the different environments. The reason why it is important tosee what materials can endure certain environments is because if the wrong metal is chosen forthe wrong environment, it can lead to safety hazards. One example where choosing the correctmetal is important is body implants. Since engineers know that steel is a corrosive metal, itwould not be safe for engineers to design body implants using steal. Since titanium has highcorrosion resistance, this makes it a safer metal to use in body implants. Overall, controllingcorrosion is really important because it can not only affect the objects that are constructed byengineers, but also cause safety hazards to the general public.Procedure1.The team was provided with samples of 1018 steel and brass. Upon receiving thesamples, a metallographic observation was conducted after the samples were polishedand grinded using 400 grit sandpaper, 600 grit sandpaper, and 1 micron powder.
