WebFeb 11, 2024 · This study focuses on the primary and secondary passivation layers applied to the state-of-the-art power devices and their influence on reliability. Power diodes assembled in standard module packages are used as test vehicles, and high-voltage temperature humidity bias tests are performed to stress the structures. WebPassivation of the surface of Mg is the simplest approach in surface modification. Passivation of commercially pure Mg (99.9% purity) by soaking in 1 M NaOH for 24 h or in modified SBF (m-SBF) at 37 °C for 5 days was explored by Lorenz et al. (2009) as a possible means of surface modification of Mg.
