Surface degradation of steel is one of the key problems of steel end user because of the electrochemical reaction at the steel surface caused by atmospheric weather condition. The major problem with steel is its surface degradation because of the electrochemical reaction at the surface from the atmospheric weather condition. To address this issue, zirconium diboride anticorrosive film has been fabricated on stainless steel by the chemical process. The synthesis of ZrB2 (~ 150 nm) has been carried out at via reaction of ZrO2 nanoparticles (10 nm) with amorphous boron at 1200 °C under argon atmosphere. The scalable doctor blade technique has been employed for the fabrication of ZrB2 film. The electrochemical performance, viz linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS) studies of ZrB2 on 304 grade stainless steel (SS), shows highly anticorrosive behaviour with excellent protection efficiency (up to 98% in acidic media) as compared to bare 304SS in neutral, acidic and alkaline media.

二硼化锆的合成及其在恶劣环境下不锈钢表面防护中的应用
由于大气气候条件引起的钢表面电化学反应,钢的表面降解是钢最终用户的关键问题之一。钢的主要问题是由于大气天气条件引起的表面电化学反应导致其表面退化。为了解决这个问题,已经通过化学方法在不锈钢上制造了二硼化锆防腐膜。ZrB 2(〜150 nm)的合成是在1200°C的氩气气氛下,通过ZrO 2纳米颗粒(10 nm)与无定形硼的反应进行的。可缩放刮墨刀技术已用于ZrB 2的制造电影。ZrB 2在304级不锈钢(SS)上的电化学性能,即线性扫描伏安法(LSV)和电化学阻抗谱(EIS)研究显示出高度的防腐蚀性能和出色的保护效率(在酸性介质中可达98%)在中性,酸性和碱性介质中裸露304SS。
