腐蚀作用

Acids are chemical compounds that, in water solution, have a sharp taste, a corrosive action on metals, and the ability to turn certain blue vegetable dyes red.

酸是一种化合物，它在溶于水时具有强烈的气味，它对金属具有腐蚀的作用，并且它具有把某些蓝色植物染料变红的能力。

In acid and salt solution,TiN shows an excell ent corrosion resistance after 100 h immersing test.TiN coating acted as a physi cal barrier between the stainless steel and corrosion media.The corrosion proces s initiated from the pinhole and the corrosion process under the coating is very similar to the pit corrosion form.

结果表明：TiN涂层可以提高材料在中性和酸性溶液中的耐蚀性能，TiN涂层的保护机制为物理屏障作用；镀层的微观结构缺陷是涂层失效的主要原因，涂层下金属的腐蚀行为与孔蚀类似。

Thus, in the present paper, weight-loss experiments and electrochemical measurements were performed in simulated sea mud cells to help solve this problem.

为此，本文对管线钢进行了模拟海泥环境下的失重实验和电化学测量，以探讨海泥环境下管线钢的腐蚀行为和可能的电化学作用机制。

But CMP technology can obtain the glabrous and smooth plane in virtue of mechanical grinding and chemical eroding.

而化学机械平面抛光技术是借助机械磨削和化学腐蚀的共同作用而使工件表面形成光洁平坦平面。

Employing the Nernst Equation the electrode potential of any possible corrosion galvanic cell may be calculated.

本文作用的方法是基于Nernst方程计算出可能形成的电极电位，再根据电位的高低判断出可能的氧化剂，从而分析出金属腐蚀的原因。
