Pulse Reverse Current Electrodeposition of Composite Coatings

本研究的目标是开发一种制备具有强组成梯度的复合涂层的方法。事实证明，这种涂层非常有用，因为它们的物理性能随着深度的变化而不断变化。因此，复合涂层提供了金属和陶瓷等不同材料之间的平稳过渡。探索的方法是将电解共沉积与脉冲逆流电镀相结合。通过对波形的仔细控制，提出了电解PRC共沉积可以提高和降低粒子与金属的比例，而不是直流电镀。这一创新具有在电镀行业生产新型和改进涂层的潜力。

The goal of this research is to develop a method for producing composite coatings with strong compositional gradients. Such coatings have proven extremely useful because their physical properties change continuously with depth. Composite coatings thus provide a smooth transition between disparate materials such as metal and ceramics. The method to be explored combines electrolytic codeposition with pulse reverse current (PRC) electroplating. By careful control of the waveform, it is proposed to demonstrate that electrolytic PRC codeposition can both enhance and depress the ratio of particle to metal deposited over that found from codeposition by means of direct current plating. This innovation has the potential to produce novel and improved coatings in the electroplating industry.
