Pulse Reverse Current Electrodeposition of Composite Coatings

本研究的目的是开发一种生产具有强成分梯度的复合涂层的方法。这种涂层已被证明是非常有用的，因为它们的物理性质随深度不断变化。因此，复合涂层在不同的材料（如金属和陶瓷）之间提供了平滑的过渡。探索将电解共沉积与脉冲逆流电镀相结合的方法。通过对波形的仔细控制，可以证明电解PRC共沉积可以提高和降低沉积的颗粒与金属的比率，而不是通过直流电镀的共沉积。这一创新有可能在电镀工业中产生新的和改进的涂层。

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.
