Název v původním jazyce

Comparative study of PVD techniques for tungsten deposition onto graphite substrate for fusion application

Popis výsledku v původním jazyce

Graphite tiles are used as heat shields to protect components exposed to high-temperature plasma due to their high thermal resistance, and low atomic number, which reduces the maintenance requirements and the effect of plasma contamination. However, sputtering and hydrogen affinity are the main limitations for graphite. Tungsten has high energy threshold for sputtering and resistance to chemical erosion. Application of tungsten layer on graphite substrate may overcome graphite's limitations. This study explores the HiPIMS technique for depositing tungsten coating and tungsten coating with molybdenum interlayers onto graphite substrates. The aim was to study the influence of surface roughness on the adhesion, mechanical properties, and microstructure of coatings to optimize coated graphite for plasma-facing materials.
