仿型砂轮电沉积工艺研究

摘要：复合电沉积法是一种操作方便，成本较低，易实现自动化、机械化的工艺方法。随着时代的发展，电沉积法越来越频繁的用于仿形砂轮的制备。本文采用3因素3水平的正交实验，围绕电铸温度，上砂时间，上砂电流密度等因素进行复合电沉积砂轮工艺的研究。测试了砂轮的表面露出高度，发现当上砂时间为400min，温度为47～53℃，电流密度为1.5A/dm2时制备的砂轮表面露出高度最小。通过高温循环氧化实验，发现当上砂时间为400min，温度为54～60℃，上砂电流密度为2A/dm2时砂轮的抗高温循环氧化能力最强。通过静态腐蚀浸泡实验，发现当上砂电流密度为1A/dm2，温度为47～53℃，上砂时间为200min时砂轮的耐腐蚀性最好。

Title Study on electrodeposition process of profiled grinding Wheel.

Abstract：Electrodeposition is a process method, which is convenience, less expensive, easy to achieve automated and mechanized. With the development of the times, electrodeposition is more and more frequent used on the preparation of profiled grinding wheel. With three factors and three levels orthogonal experiments, this study focuses on electrodeposition temperature, time on the sand and the current density of electrodeposition to improve profiled grinding wheel. It found that when the sand time 400 min, at 47～53 ℃, with the current density on 1.5A/dm2 the exposed surface would become least. High temperature cyclic oxidation experiment found that when the sand time is 400 min, at 54～60 ℃ with the current density of the sand on 2A/dm2 high temperature oxidation resistance would be best . Static corrosion immersion test found that when the current density of the sand is 1A/dm2 ,at 47～53 ℃ with 200 min sand time corrosion resistance of the wheel would be best.
