In the first part, samples of aluminum, copper and iron were immersed in concentrated sulfuric acid for ten minute intervals. After each ten minute interval, the weight of the samples were recorded. This process was done four times after which the corrosion rates were then found. Finally the corrosion rates versus the time were then plotted on a graph. In the second part of the experiment, a magnesium sample was connected to the apparatus and readings of the current were taken at regular intervals after which the graph of current versus time was plotted. Finally, the expected life of the magnesium anode was calculated for each reading. Part A (Corrosion) Introduction: Corrosion is a spontaneous degradation that a metal undergoes when exposed to an environmental factor such as air, water, corrosive chemicals or soil. Corrosion is caused by an electrochemical reaction that takes place between the metal and the environment. Many of the severe corrosion problems encountered in the chemical and processing industries involve acids. However, in some cases, electrochemical cells may be useful when it is used to deliberately create an electro-protective coating on materials. In this experiment, concentrated sulfuric acid was used. Theory: R=W At R: corrosion rate (cm / hr). W: weight loss (in gm to the nearest mg). A: area to the nearest 0.01cm2. t: the time of exposure in hours to the nearest 0.01 hr. 4 Experimental procedure: 1) Place 250 ml of hydrochloric acid into a beaker in a fume hood with extreme care. 2) Weigh the copper specimen. 3) Use a suitable wire to hang the specimen and clamp it to a stand (hold the specimen through the wire). 4) Immerse the steel specimen in the acid and make sure that the entire specimen is immersed in the acid solution. 5) After 10 minutes, take the sample out of the acid, wash it and then dry it thoroughly. 6) Weigh the sample. 7) Repeat steps 2-6 for the sample 3 more times. 8) Repeat all the above steps for samples of aluminum and iron. 5 Data: Metal Aluminum Copper Iron Length (cm) 4 4.08 2.94 Width (cm) 2.15 2.15 1.06 Thickness (cm) 0.3 0.52 0.0 Surface Area, A (cm2) 20.89 10.39 17.54 Aluminum Area (m2) Weight weight loss (g) (g) 6.62 0 6.619 0.001 6.618 0.001 6.617 0.001 6.616 0.001 20.89 Time (min) 0 10 20 30 40 corrosion rate 0.000281587 0.00014506 9.57396E-05 7.14475E-05 time (hrs) 0 0.17 0.33 0.5 0.67 Iron Area (m2) Weight (g) 6.359 6.358 6.358 6.358 6.358 weight loss (g) 0 0.001 0 0 0 17.54 Time (min) 0 10 20 30 40 corrosion rate 0.000335368 0 0 0 time (hrs) 0 0.17 0.33 0.5 0.67 Copper Area 2 (m ) Weight (g) 12.483 12.483 12.482 12.481 12.481 loss weight (g) 0 0 0.001 0.001 0 10.39 Time (min) 0 10 20 30 40 corrosion rate 0 0.000291656 0.000192493 0 time (hrs) 0 0.17 0.33 0.5 0.67 6 Corrosion rate Vs time 0.0004 0.00035 0.0003 Corrosion rate 0.00025 0.0002 0.00015 0.0001 0.00005 0 -0.00005 0 0.2 0.4 Time(hrs) 0.6 0.8 Aluminum Iron Copper Calculations: (Sample calculation) Corrosion rate of aluminum after 10 minutes is calculated by: R= 0.001 (20.89)(0.17) = 0.000281587 The corrosion rates of the other times and samples can be found in a similar manner by using the given formula. Part B (Cathodic protection) Introduction: Cathodic protection is one of a number of corrosion control practices that includes the application of protective coatings, and improved metallurgical techniques. To prevent corrosion, a common procedure is to introduce a piece of another metal, as a sacrificial anode, in contact with the metal to be protected. The sacrificial anode is composed of a metal, which has a greater tendency to corrode than does the metal to be protected; as a result, the sacrificial anode corrodes instead of the protected metal. The sacrificial anode can then be replaced periodically to maintain the protection. 7 Theory: Lm = 42.81*W I Lm = Life of magnesium anode, year W = Weight of anode, pounds i = milliampere output of anode Experimental procedure: 1) Set up the apparatus. 2) Put a weak salt solution in the beaker. 3) Record the current with each interval of time. As the cell becomes polarized the current will drop. 4) Do not disturb the corrosion products. These products will be seen to be distributed in the direction of current flow. The magnesium will dull and the unprotected pipe will corrode whilst the cathodic pipe remains protected. Data: Time (s) 0 20 40 60 80 100 120 140 160 180 200 Current (mA) 68 66 64 63 62 61 61 60 57.5 57 59 Life 0.009695 0.009989 0.010301 0.010465 0.010633 0.010808 0.010808 0.010988 0.011466 0.011566 0.011174 Weight of the magnesium sample = 0.0154lb 8 Cathodic protection 70 68 Current(mA) 66 64 62 60 58 56 0 100 Time (s) 200 300 Cathodic protection Calculations: (Sample calculation) L = 42.81(0.0154) = 0.011566 57 Discussion and Conclusion: In part (A), the more time the copper, aluminum and iron samples spend in the concentrated sulfuric acid, the more the weights of these three samples decrease. The graphs for the rate of corrosion versus time are all similar. The graphs and the readings clearly show that as the time increases, the corrosion rates for each sample decreases. Thus the conclusion is that the more time that the samples spend in the acid, the more the corrosion rate and weight increase. In part (B) of the experiment, a magnesium sample was used in the cathodic protection experiment and for every increase in time, the corresponding value of the current in milli-amperes was recorded after which a graph of current versus time was plotted. As can be seen from the graph and the table, it was concluded that as the time increased, there was a subsequent decrease in current. The expected life of the sample also increases along with the time. 9 References (Part A): 1) William D.
