The Study and Prediction of Corrosion Rate of Ductile Iron in Cassava Fluid Using Java Oriented Program

Abstract

This work studied the corrosion rate of ductile iron in cassava fluid and developed prediction software for the process using Java programming language. The work measured the corrosion effect of the cyanotic cassava fluid on ductile iron by determining the corrosion rate using gravimetric method. Cassava tubers were procured, grated and their fluid were manually squeezed out. The ductile iron samples used were slightly machined and treated with silicon carbide papers and were immersed in the cassava fluid for a period of 30 days. The corrosion specimens were weighed with a digital chemical weighing balance and recorded, this continued at regular interval of 5 days. The results achieved from the experiment were used to model and simulate a Java-oriented program that is capable of predicting the longtime effect of corrosion rate of ductile iron in cassava fluid. Exposure time in days and specific area of samples are the required parameters to generate corrosion rate, weight lost, and the graph of weight loss versus exposure time using the software. This Java application was also expanded to accommodate other metals in different environments.
