Coatings of Ni-B have gained significant importance in various industries owing to their major role in improving mechanical properties including hardness, conductivity, and wear resistance. Despite all these characteristic features, there is still the need for a lot of modifications. This is to improve the properties of the coating so as to increase their durability and overall performance. The current study is based on development of Ni-B-V₂O₅ composite coating on mild steel substrate through the electrodeposition technique and the investigation of mechanical and anti-corrosive properties of the formed coating. The incorporation of V₂O₅ particles into the composite coating was confirmed by energy dispersive spectroscopy. X-ray diffraction pattern showed amorphous nature of electrodeposited Ni-B matrix, while the crystalline nature improved with the addition of V₂O₅ particles to the composite. Field emission scanning electron microscopy and atomic force microscopic studies clearly indicated that the addition of V₂O₅ particles to the Ni-B coating increased the surface roughness. Further studies reveal increase in the micro-hardness (by 171.11%), and elastic modulus (by 9.4%) in case of the Ni-B-V₂O₅ composite coating relative to the Ni-B coating. The enhanced micro-hardness was attributed to the inclusion of hard V₂O₅ particles into the Ni-B matrix, which in turn, may inhibit the dislocation motion in the composite. An increase in corrosion resistance (by 229%) was also experienced in the electrodeposited Ni-B-V₂O₅ composite coating in comparison to the bare Ni-B matrix, which may be due to the masking of inert V₂O₅ particles on the active region of the Ni-B composite.

由于Ni-B涂层在改善机械性能（包括硬度，电导率和耐磨性）方面起着重要作用，因此在各个行业中已变得非常重要。尽管具有所有这些特征，但仍需要进行大量修改。这是为了改善涂层的性能，从而增加其耐久性和整体性能。当前的研究是基于通过电沉积技术在低碳钢基底上开发Ni-BV ₂ O ₅复合涂层以及对所形成的涂层的机械性能和耐腐蚀性能进行研究的。V ₂ O ₅的掺入通过能量色散光谱法确认颗粒进入复合涂层。X射线衍射图显示了电沉积的Ni-B基体的非晶态性质，而通过向复合物中添加V ₂ O ₅颗粒改善了晶体性质。场发射扫描电子显微镜和原子力显微镜研究清楚地表明，向Ni-B涂层中添加V ₂ O ₅颗粒会增加表面粗糙度。进一步的研究表明，相对于Ni-B涂层，Ni-BV ₂ O ₅复合涂层的显微硬度提高了171.11％，弹性模量提高了9.4％。显微硬度的提高归因于硬V的加入₂ O ₅颗粒进入Ni-B基体，这反过来又会抑制复合物中的位错运动。与裸露的Ni-B基体相比，电沉积的Ni-BV ₂ O ₅复合涂层中的耐蚀性也提高了（229％），这可能是由于惰性V ₂ O ₅颗粒被掩盖了。 Ni-B复合材料的有效区域。
