作为美国ITER研究和开发活动的一部分，正在研究将钨包覆层应用于铜的方法，沿着用于破坏能量转储的蒸发冷却钨的开发。正在尝试通过使用镍或钛中间层的扩散结合来连接。通过使用钨和铜的功能梯度层以及作为连续相的铜来实现胶层残余应力的减少。使用真空等离子喷涂、液相烧结和粉末热等静压制造层。初步金相结果是有希望的，与制造的拉伸和高热通量标本的计划。计划用镁和锂直接渗透74%致密的钨。
As part of the US ITER research and development activities, approaches to applying tungsten clads to copper, along with the development of a transpiration-cooled tungsten for use as a disruption energy dump, are being investigated. Joining is being attempted by diffusion bonding using nickel or titanium interlayers. Reduction in bondline residual stresses is being accomplished by use of functionally graded layers of tungsten and copper with copper as the continuous phase. Layers are being fabricated using vacuum plasma spray, liquid phase sintering and powder hot isostatic pressing. Initial metallographic results are promising, with fabrication of tensile and high heat flux specimens planned. Direct infiltration of 74% dense tungsten with magnesium and lithium is planned.
