本文综述了等离子体表面的溅射侵蚀/再沉积模型。介绍了WBC蒙特卡罗杂质传输代码的基础知识。给出了液锡聚变反应堆导流器腐蚀的实例分析。总结了多年来对候选导向器和第一壁涂层材料（Li, Be， C， W等）的侵蚀研究，表明低z固体材料普遍存在严重的侵蚀问题，而高z材料和液体导向器表面的结果令人鼓舞。讨论了未来的目标，例如超级计算机建模。
This paper reviews sputtering erosion/redeposition modeling for plasma facing surfaces. Basics of the WBC Monte Carlo impurity transport code are described. An example analysis is shown for erosion of a liquid tin fusion reactor divertor. Multiyear erosion studies of candidate divertor and first wall coating materials (Li, Be, C, W, etc.) are summarized—showing generally serious erosion concerns for low-Z solid materials, and encouraging results for high-Z materials and liquid divertor surfaces. Future goals are discussed, e.g. for supercomputer modeling.
