Infiltration sintering properties of Ni-4B-4Si(wt.%)alloy powders

摘要：

　　The Ni-4B-4Si(wt.%)alloy powders were infiltrated into the nickel skeletons,the effects of sintering temperatures(1050-1150℃)and skeletons(loose and compact nickel powders)on the microstructures and hardness of the sintered alloys were investigated.The Ni-B-Si alloy sintered at 1100 ℃ consisted of γ-Ni and Ni3B,and Si mainly solid soluted in the γ-Ni.The loose nickel powders favored to the infiltration of Ni-B-Si liquid alloy into the nickel skeletons,the sintered alloys exhibited dense microstructures and good interfacial bonding with Ni substrates.The interfacial hardness was equal to that of the sintered alloys and Ni substrates.Loose nickel powders ensured the density and interfacial bonding of the sintered alloys,the infiltration sintering process can be simplified and easily applied to practice.
