We, by adding the appropriate amount of nickel, usually, it s very easy to rust steel, stop, carbon steel, rare dissolved or diluted HNO3 in concentrated H2SO4 phen omenon almost completely iron, aluminum, or concentrated HNO3 quickly chrome you know that you are dissolved in sulfuric acid, stainless steel. I obey improve the chemical stability of the phenomenon known as passivation significantly metals or alloys, a number of factors. Metal passivation phenomenon caused by (chemical solution) passivating agent several called chemical passivation. load factor power plant
You can HNO3, to H2SO4, HClO3, K2Cr2O7 concentrated concentration, potassium permanganate oxidation agent, the metal passivation. After passivation of the metal, the original characteristics of the iron as a passivation of the copper salt that is copper displaced such to be lost, the electrode potential moves in the positive direction. In addition, The electrochemical method, allowing Fe of H2SO4 solution, applied current anodic polarization, use of the instrument of constant rising p otential of iron to some extent, the passivation of metals such as iron dynamics as an anode. Metal passivation phenomenon caused by the anodic polarization are called electrochemical passivation or anode passivation.
The metal, metal, not to protect the metal from corrosion to ensure the need to prevent passivation as chemical and power electroplating such normally dissolved and involved in the reaction sometimes are passivated.road load power
