Abstract
Tungsten is a prime candidate material for a plasma-facing material in a fusion reactor. Tungsten coating on ferritic-martensitic steel by a plasma spray coating method using 55 kW vacuum plasma spray system was fabricated and evaluated. Surface roughness, hardness, porosity, micro-structure and chemical characteristics of the tungsten coating layer were analyzed. Also, heat/particle flux tests were performed at 10 MW/m2 up to 60 sec using the plasma spray gun of the vacuum plasma spray system and microstructures were evaluated. The results showed soundness of the bonding layer between the substrate and the tungsten coating layer.
