摘要

摘要增材制造业在许多行业中都在经历一场针对各种材料的崛起。工艺主要针对聚合物和金属开发。对于陶瓷、硬质合金，尤其是金属陶瓷，只有少数几种添加剂工艺适用。基于粉末的技术粘结剂喷射是这些合适的工艺之一，具有高生产率和相对低的生坯密度。在本研究中，首次通过粘结剂喷射法印刷了TiCN基金属陶瓷。讨论了金属陶瓷粉末的形态和成分对印刷和烧结零件的体积密度和材料性能的影响的复杂性。所研究的TiCN基金属陶瓷成分代表了不同的Ni和Mo2C含量。本研究的要点是进一步调整原材料的比例以获得良好的烧结性能，以及它们对微观结构的影响，以及作为不同烧结温度的函数。

Binder-jetting of TiCN-based cermets

ABSTRACT Additive Manufacturing is experiencing an upswing in many sectors of industry for a broad variety of materials. Processes are mainly developed for polymers and metals. For ceramics, hardmetals and especially cermets there are only a few additive processes suitable. The powder-based technique Binder-Jetting is one of these suitable processes with high productivity and relatively low green density. Within this study, TiCN-based cermets are printed by Binder-Jetting for the first time. The complexity of influences of the morphology and composition of cermet powders are discussed in regard to bulk density and material properties of printed and sintered parts. Studied TiCN-based cermet compositions represent different Ni and Mo2C contents. Main points of this investigation are further the adjustment of ratio of the raw materials for good sintering behaviour and their influence on the microstructures and as a function of varied sintering temperatures.
