Layered and Graded Coatings as Plasma Facing Materials for Fusion in LSCPM

摘要：

　　This paper reports some new progresses on layered and graded coatings for plasma facing materials in fusion devices in Laboratory of Special Ceramics and Powder Metallurgy (LSCPM),University of Science and Technology Beijing (USTB),China.They included tungsten coatings made be various particle sizes of initial feedstock and interlayers and boron carbide graded coatings.All the coatings were fabricated on the oxygen free copper by plasma spraying.The microstructures and properties were investigated for PFM.Water quenching and high heat loading experiments were also carried out to estimate the thermal performance of these coatings.
