1.	Which of the following is/are correct regarding passivation?(a) It is defined as the loss of reactivity at certain conditions(b) Usually results in the formation of the oxide layer(c) The corrosion rates are relatively low(d) It is defined as loss of reactivity at certain conditions usually due to the formation of the oxide layer and corrosion rates are relatively lowI had been asked this question in a national level competition.My question is based upon Modern Theory Principles topic in division Modern Theory Principles of Corrosion Engineering
Answer» CORRECT CHOICE is (d) It is defined as loss of reactivity at certain conditions usually due to the formation of the OXIDE layer and CORROSION RATES are relatively low For explanation: Passivation is defined as the loss of reactivity of metals/alloys at certain conditions usually due to the formation of the oxide layer and corrosion rates are relatively low.
