AI Technical Summary
Technical Problem
Traditional (Ti,W)C-based cermet materials are ferromagnetic, which limits their application in the electronics industry and magnetic material processing.
Method used
CoxCryNiz alloy was used as a binder, combined with (Ti,W)C-based ceramic powder and auxiliary agents such as Mo, TiC, and TiN, to prepare non-magnetic (Ti,W)C-based cermets through vacuum sintering and ball milling. The antiferromagnetic element Cr was used to weaken the magnetism, and the paramagnetic elements Ti and W were combined to further reduce the magnetism.
Benefits of technology
(Ti,W)C-based cermets with superior non-magnetic properties and good mechanical properties were prepared, which are suitable for processing non-magnetic molds and magnetic material workpieces.

Abstract
本发明公开了一种无磁(Ti,W)C基金属陶瓷及其制备方法，涉及粉末冶金技术领域，所述无磁(Ti,W)C基金属陶瓷包括：粘结剂，以及基体材料，所述粘结剂包括CoxCryNiz合金，其中x为(0.2～1)，y为(0.8～1)，z为(0.2～1)，所述基体材料包括(Ti,W)C基陶瓷粉末。本发明将CoxCryNiz合金作为粘结剂提供韧性和塑性，将(Ti,W)C基陶瓷材料作为基体材料提供硬度和强度，此外，利用CoxCryNiz合金中的反铁磁性元素Cr减弱金属陶瓷的磁性，(Ti,W)C基陶瓷中的顺磁性元素Ti和W进一步减弱金属陶瓷的磁性，所制得的(Ti,W)C基金属陶瓷具备无磁性和良好的力学性能。
