多孔不锈钢的制备及其在注塑模具中的应用
Preparation of Porous Stainless Steel and Its Application in Injection Mold
摘要
Abstract
Porous stainless steel was prepared by gel casting and microwave sintering.Effects of solid content on the properties of slurry and green body were studied,and different results between freeze drying and traditional drying were compared.Macroscopic properties and internal porosities of the porous stainless steel were investigated and compared with PM35 porous mold steel,which was then served as injection mold core.The results show that optimum fluidity of slurry and high strength of green body can be accessed when solid content is 56％.Compared with traditional drying,shrinkage of the green body achieved by freeze drying is more uniform,and crack is seldom occurred.Pore morphology,porosity,average pore size and permeability of the porous stainless steel are similar to that of PM35 porous mold steel.Surface rough of injection part that produced via the PSS core can be up to Ra1.1.The porous stainless steel,prepared by gel casting and microwave sintering,can solve trapped gas problem.Meanwhile,it can ensure surface quality of injection parts,simplify mold structure,and reduce production cost.关键词
