Abstract

General quality problems in electroplating are the nickel plating layer peeling and bubble problem. Nickel plating layer peeling and bubble problem is mainly caused by bad combining of the coating and the substrate. This paper studies the heat treatment quality of the nickel plating layer and the influence of welding performance, ceramic shell surface nickel plating respectively after a 400 °C, 600 °C and without heat treatment, heat treatment using scanning electron microscope observation of morphology, through the analysis of coating microstructure, preliminary discussion on the mechanism of the influence of heat treatment temperature on the coating hardness and so on performance.

热处理对镀层质量及镀镍后焊接可靠性的影响研究
电镀中常见的质量问题是镀镍层剥落和起泡问题。镀镍层剥落和起泡问题主要是由于镀层与基体结合不良造成的。本文研究了镀镍层的热处理质量及对焊接性能的影响,陶瓷壳表面镀镍分别经过400℃、600℃和未经热处理,采用扫描电镜观察热处理后的形貌,通过对镀层微观结构的分析,初步探讨了热处理温度对镀层硬度等性能的影响机理。
