微粒射流电沉积制备金属薄膜的工艺设计
摘要这次设计的核心工艺是微粒射流电沉积技术和薄膜技术。其中微粒射流电沉积技术是一种低成本的涂层制备技术，它是将电解液喷到工件表面达到形成沉积层的目的；而薄膜技术是采用特殊方法在材料表面沉积或者制备一层与材料的性质完全相同物质的技术。80319
目前制备薄膜的方法有许多，比如：物理气象沉积法，化学气象沉积法，溶液镀膜法等等，但是这些方法在制备过程中遇到了一些问题：制备的薄膜不均匀，耗费太高等等；与之相比，微粒射流电沉积制备薄膜就有以下明显的优势：可在复杂的机体上均匀沉积；可以精确地控制沉积沉的厚度；沉积速度可以通过电流和电解液流速来实现控制；而且这种方法投资少，方法简单，适用于工业化大生产。
通过电沉积方法在零件机体上制备薄膜既保证了较好的耐磨性，耐腐蚀性，又具有低磨损率和低摩擦系数，因此特别适用于薄膜的制备。本次实验就是利用微粒射流电沉积法的优良特性来解决其他技术不能制备的薄膜或者制备的薄膜达不到要求的难题。

Process design on metal thin films prepared by electrnic deposition of micro particles
Abstract: Particle jet electrodeposition technique and thin film technology is the core technology of the design。 The particle jet electrodeposition technique is a kind of low cost of coating preparation technology, it is will reach electrolyte sprayed to the surface of the workpiece to form a sedimentary layer and thin film technology is using a special method in material surface deposition or prepared with a layer of material properties that are completely the same material technology。
At present, the preparation of the film there are many, such as: physical vapor deposition, chemical vapor deposition solution coating method and so on, but these methods in the preparation process has encountered some problems: preparation of the film is not uniform, cost too high, and so on; compared with, particle jet electrodeposited films has the following obvious advantages: uniform deposition in complex organisms; can accurately control the thickness of deposited heavy; deposition rate can control is achieved by current and electrolyte flow rate; and less investment in this method。 The method is simple and applicable to industrialized production。
By electrodeposition method in body parts of films can not only ensure the better wear resistance, corrosion resistance, and low wear rate and the friction coefficient is low, it is especially suited to thin films prepared。 This experiment is the use of the excellent characteristics of particle jet electrodeposition method to solve the he cannot be prepared films or preparation of thin films is not up to the requirements of the problem。
