表面化学揭示了腐蚀的秘密太阳能利用：铁锈和水制氢储能研究养花小技巧：铁锈到底能不能浇花？掌握好方法，自然会有好效果
金属加工件在生产加工及运输的过程中,离开了防锈剂,工件就很容易生锈.所谓锈是由于氧和水作用在金属表面生成氧化物和氢氧化物的混合物,铁锈是红色的,铜锈是绿色的,而。铁锈工具最新消息，还有铁锈战争mod制作工具，铁锈战争mod编辑器，铁锈战争工具等首先,用钢丝刷等工具对钢材表面进行抛光,以清除疏松或拉长的氧化物,铁锈,焊渣等铁锈主要由三氧化二铁水合物Fe2O3·nH2O和氢氧化铁（FeO（OH）, Fe（OH）3）组成。其他金属亦会被氧化，但是通常不称为“鏽”。足够的时间后，在氧气和水化学方法主要是利用酸与铁锈发生化学反应，从而达到除锈的目的。通过实验也可说明当其它条件相同时，稀硫酸与金属氧化物的反应速率比盐酸慢。锈是一个化学术语，通常指金属（包含合金）表面所产生的氧化物，常见的有：铁锈，铜锈，铝锈等等。但未必所有金属的氧化物都称为“锈”。概言之，常见的金属才会用“锈”来尽管铁锈和相关的铁矿是地球表面生命的一部分，但它们形成的环境相当复杂和多样。铁锈通常由铁氧化物（iron oxides）和铁氢氧化物（iron hydroxides）这项技术的关键组成部分实际上就是水和金属氧化物,如氧化铁也就是通常称之为铁锈的物质。洛桑联邦理工学院的Kevin Sivula和他的同事们有意地为自己 1 / 4 网上疯传铁锈水浇花的效果非常好，特别是用来浇灌茉莉花这类喜酸的是的，当水锈注入土壤时，土壤中的其他硫化物与一部分氧化铁发生化学

Surface corrosion involves a series of redox reactions that are catalyzed by the presence of ions. On infrastructure surfaces and in complex and natural environments, iron surfaces readily undergo redox reactions, impacting chemical processes. In this study, the effect of how cations influence the formation of the mineral scale on iron surfaces and its connection to surface corrosion was investigated in CaCl 2 aq and NaCl aq electrolytes. PM-IRRAS, attenuated total reflectance—Fourier transformed infrared spectroscopy, and X-ray photoelectron spectroscopy show that after the adsorption of atmospheric O 2 and CO 2 , calcium carbonate CaCO 3 in the form of calcite and aragonite was produced on iron in the presence of CaCl 2 aq , whereas siderite FeCO 3 was produced on the surface of iron in the presence of NaCl aq. In situ liquid AFM was used to measure the surface roughness in CaCl 2 aq and NaCl aq , as an estimation of the corrosion rate. In CaCl 2 aq , Fe was found to corrode faster than Fe in NaCl aq due to more ions at equimolar concentrations. This indicates that the cation does not affect the type of mineral grown on the Fe surface in the region completely submerged in the electrolyte. These results suggest that the cations play a unique role in the initial stages of corrosion at the interface region, influencing the uptake of atmospheric CO 2 and mineral nucleation. The knowledge gained from these interfacial reactions are important for understanding the connection between surface corrosion, mineral grown, and CO 2 capture for sequestration.
