摘要

非晶态合金Fe的耐蚀性变化NiB研究了在0.1N H2SO4中由于铬含量(0至14atmol%)的提高而引起的P:铬含量越高,腐蚀电流密度越低,腐蚀电位越高。含有10at%铬的合金显示出自发钝化。在20–83°C的温度范围内,根据Arrhénius图的斜率估计了有源和无源电流的激活能。

Effet du chrome sur la resistance a la corrosion d'alliages amorphes FeNiBP dans H2SO4 0,1 N

Change in the corrosion resistance of amorphous alloys FeNiBP due to the improve in chromium content (0 to 14 atome %) has been investigated in 0.1 N H2SO4: the higher the chromium content, the lower the corrosion current density and the higher the corrosion potential.

The alloy containing 10 at % chromium shows spontaneous passivation.

In the temperature range 20–83°C, the activation energies of the active and passive currents have been estimated from the slope of the Arrhénius plots.
