Synthesis And Characterization Of Hypothetical Superhard C3N4 Coatings (SGER Award)

在SGER奖下进行的这项探索性研究将试图 在金属基底上存款β-C 3 N 4。 化合物的 从理论上已经预言了 这也表明它可能比金刚石更硬。 等离子体增强化学气相沉积 技术将尝试在（0001）面的单一 Hf和Zr的晶体，其与晶体紧密匹配 化合物的结构，也有很强的键， 碳和氮 所得涂层将是 通过晶体学、金相学和 摩擦学技术

This exploratory study under an SGER award will attempt to deposit beta-C3N4 on metal substrates. The compound's existence has been predicted from theoretical considerations which also indicate that it may be harder than diamond. Deposition by plasma-enhanced chemical vapor deposition techniques will be attempted on the (0001) faces of single crystals of Hf and Zr, which closely match the crystal structure of the compound and also have strong bonds with both carbon and nitrogen. The resultant coatings will be characterized by crystallographic, metallographic and tribological techniques.
