Abstract

Language:

This study investigates the formation of magnesium oxide (MgO) coatings on nickel superalloy substrates through an electrolytic processing method. The objective was to assess the effectiveness of a two-step coating process, which included cathodic electrolytic deposition of magnesium hydroxide (MgOH) followed by heat treatment to calcinate and sinter the deposit. X-ray diffraction and scanning electron microscopy were employed to analyze the morphology and composition of the deposits prior to and following heat treatment. The results indicate that the deposition parameters significantly influence both the deposition yields and the morphological characteristics of the MgO coatings. This research contributes to the development of efficient low-temperature methods for fabricating metal ceramic coatings that exhibit uniform microstructures and enhanced sinterability, catering to applications in industries such as automotive and aerospace. These findings may offer insights into improving protective coating technologies for high-performance materials.
