1.	What are the uses of corrosion rate estimation of materials in daily life?(a) To predict the life time of a component(b) To compare the corrosive-resistant of materials(c) To increases the corrosion rate(d) To predict the life time and to compare the corrosive resistant of materialsI have been asked this question in my homework.I want to ask this question from Corrosion Rate Expression in division Corrosion Principles of Corrosion Engineering
Answer» Right option is (d) To predict the life time and to compare the corrosive resistant of materials To EXPLAIN: CORROSION rate expression is USED to quantify the corrosion process. This helps US to predict the life time of a component and to compare with different materials. This also helps us to change the process VARIABLES in order to decrease the corrosion rate.
