| 摘 要： | B4C，SiC and C,Cu functionally graded-materials(FGMs) have been developed by plasma spraying and hot pressing.Their high-heat flux properties have been investigated by high energy laser and electron beam for the simulation of plasma disruption process of the future fusion reactors.And a study on eroded products of B4C/Cu FGM under transient thermal load of electon beam was performed.In the experiment SEM and EDS analysis indicated that B4C and SiC were decomposed.Carbon was preferentially evaporated under high thermal load,and a part of Si and Cu were melted,in addition,the splash of melted metal and the particle emission of brittle destruction were also found.Fifferent erosive behaviors of carbon-based materials(CBMs)caused by laser and electron beam were also discussed.

| Abstract: | B4C, SiC and C, Cu functionally graded-materials (FGMs) have been developed by plasma spraying and hot pressing. Their high-heat flux properties have been investigated by high energy laser and electron beam for the simulation of plasma disruption process of the future fusion reactors, And a study on eroded products of B4C/Cu FGM under transient thermal load of electron beam was performed. In the experiment, SEM and EDS analysis indicated that B4C and SiC were decomposed, carbon was preferentially evaporated under high thermal load, and a part of Si and Cu were melted, in addition, the splash of melted metal and the particle emission of brittle destruction were also found. Different erosive behaviors of carbon-based materials (CBMs) caused by laser and electron beam were also discussed. |
