The aspect of thermal treatment of particles and micro samples will be extended to thermochemical treatment in the next phase of the project U03. The focus will be on the targeted and reproducible transfer of nitrogen onto micro samples in a size range from few micrometers to 1 mm. Due to the time consuming diffusion process of nitrogen, a major advantage of the pre-alloying of powder samples with its small length scales can be adapted and nitrided powders can be processed to macro samples for instance by using additive manufacturing processes. The spherical micro samples and macro samples from additive manufacturing can be characterized using proper descriptors, as well as macroscopically common characteristic properties. The thermochemical treatment will initially be carried out in TGA and will be extended to a fluidized bed reactor for high throughput.

在U03项目下一阶段，颗粒和微样的热处理方面将扩展到热化学处理。重点将放在定向和可重复的氮转移到微样品上，尺寸范围从几微米到1毫米。由于氮的扩散过程耗时，因此可以适应粉末样品预合金化的主要优点，并且可以使用增材制造工艺将氮化粉末加工成宏观样品。增材制造的球形微观样品和宏观样品可以使用适当的描述符以及宏观上的共同特征性质来表征。热化学处理将首先在TGA中进行，并将扩展到高通量的流化床反应器。
