摘要

传统方法制备复杂构件的硬质合金产品难度大,成本高,影响了硬质合金的持续发展。采用挤出式3D打印成形硬质合金打印样,经溶剂脱脂、热脱脂和气压烧结制备WC-10Co硬质合金样品,研究打印参数、脱脂工艺和烧结温度对样品的显微组织与力学性能的影响。结果表明,采用不同的喷嘴尺寸,可调节打印样的表面粗糙度与尺寸精度,使用溶剂-热脱脂两步法脱脂后脱脂坯形状与尺寸稳定,烧结后该合金的组织分布均匀,在1 450 ℃烧结后合金硬度为87.3 HRA,抗弯强度超过3 500 MPa,性能媲美常规粉末冶金方法制备的合金。

Abstract

The traditional method of preparing cemented carbide products with complex components is difficult and costly, which affects the sustainable development of cemented carbide. The cemented carbide samples were formed by extrusion 3D printing. The sintered cemented carbide samples of WC-10Co were prepared by solvent degreasing, hot degreasing and air pressure sintering. The effects of printing parameters, degreasing process and sintering temperature on the microstructure and mechanical properties of the samples were studied. The results show that the surface roughness and dimensional accuracy of the printed samples can be adjusted by using different nozzle sizes. The shape and size of the blank are stable after degreasing by solvent-thermal two-step degreasing method. The microstructure of the alloy is uniformly distributed after sintering. After sintering at 1 450 ℃, the hardness of the alloy is 87.3 HRA, the bending strength is more than 3 500 MPa, and the performance is comparable to that prepared by conventional powder metallurgy method.

Key words： cemented carbide; extrusion 3D printing; solvent degreasing; bending strength; hardness
