一、腐蚀科学发展概况金属腐蚀是指金属由于化学或电化学多相反应,而使其晶格破坏变成金属化合物的过程。金属是地球上的原矿(金属的氧化物、硫化物等)经冶炼、还原而得。这种纯的金属处于自由能高位状态,所以它又有一种向原来稳定的、自由能低位状态的氧化 First, the corrosion of scientific development Overview Metal corrosion refers to the metal due to chemical or electrochemical multiphase reaction, leaving the lattice destruction of metal compounds into the process. Metal is the ore on the earth (metal oxides, sulfides, etc.) by smelting, reduction derived. This pure metal in the free energy high state, so it has a stable to the original, low energy state of oxidation
