Atmospheric plasma sprayed W coating/Detonation sprayed W-steel composite coating/steel substrate-based coating system for the tokamak first wall

To study the manufacturing method of the tungsten armored puzzle first wall of tokamak devices, the W-316 L steel (W-SS) composite coatings were fabricated on 316 L steel substrates by detonation spraying (DS) as the interlayer of pure tungsten coatings manufactured by atmospheric plasma spraying (APS).The main characteristics and performance under

A Novel Harmonic State-space Modelling Method on the Modular Multilevel Matrix Converter and Coupling Analysis

The fractional frequency transmission system is an emerging technology for long-distance wind power integration, and the modular multilevel matrix converter (M3C) is the keen equipment.Since the M3C directly connects two ac grids with different frequencies, the external and internal harmonics have complex coupling relationships with a unique dual-f
