Research on the impact of heat treatment on coating quality and reliability of welding after plating nickel

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.
