Additive Manufacturing of WC-Ni Based Cemented Carbides via Vat Photopolymerization Technology AITranslate
Abstract AITranslate
WC-Ni based cemented carbides were fabricated by vat photopolymerization(3D printing)technology.The influence of slurry composition and printing parameters on the rheological and curing properties of the slurry was investigated,as well as the properties of WC-Ni based cemented carbides.The results indicate that when the solid content of the slurry is 40 vol.%and ZN-1344 is chosen as the dispersant with an addition of 2%by mass of the powder,the rheological properties of the WC-Ni slurry meet the requirements of the additive manufacturing process.And the viscosity of the slurry reaches 2.718 Pa·s at a shear rate of 100 s-1.When the printing parameters are set to 0.01 mm hatch spacing,90%laser power,and 2000 mm/s scanning speed,the maximum single-layer curing depth of the slurry reaches 144μm.The calculation model for the single-layer curing depth of the slurry is obtained by data fitting using the response surface methodology(RSM),and the calculated value has a deviation of 3.4%compared with the actual value,demonstrating its capability of theoretical prediction.The density and relative density of WC-15%Ni cemented carbide prepared via vat photopolymerization can reach a maximum of 13.51 g/cm3 and 96.5%,respectively.The addition of 1 wt.%grain growth inhibitor Cr3C2 significantly improves the Vickers hardness of the cemented carbide to 945 HV30,approaching the hardness of traditional cemented carbides with equivalent Ni content but without Cr3C2.
