In this work manganese cobalt spinel (MnCo₂O₄) coatings were deposited on steel substrates by spray pyrolysis at 390 °C. This is at much lower temperatures than previously reported (typically in excess of 900 °C). It was possible to produce coatings with well controlled thickness (2-5-10 μm). The as-deposited coatings were evaluated for their microstructural changes and electrical conductivity up to 800 °C. Results confirm the formation of a single phase spinel with high density and electrical conductivity. Based on the obtained results, it might be concluded that spray pyrolysis is a very promising method to develop protective coatings for steel substrates at low temperatures overcoming limitations of many other methods.

在这项工作中，锰钴尖晶石（MnCo ₂ O ₄）涂层在390°C下通过喷雾热解沉积在钢基底上。与以前报道的温度相比，该温度要低得多（通常超过900°C）。可以生产厚度控制良好的涂层（2-5-10μm）。评估了沉积后的涂层的微观结构变化和高达800°C的电导率。结果证实形成具有高密度和电导率的单相尖晶石。基于所获得的结果，可以得出结论，喷雾热解是克服许多其他方法的局限性而在低温下开发用于钢基材的保护涂层的非常有前途的方法。
