Aqueous Binder for Powder Injection Moulding (PIM) of Ti and Ti-6Al-4V Alloy Powders
Powder injection moulding has the capability to consolidate metal powders into complex shapes, which are difficult or expensive to produce by other traditional methods. This paper discusses possibilities of using an aqueous based binder as a more effective, inexpensive an d environmentally friendly binder for consolidation of Ti-6A-14V powders. The properties of the aqueous based binder and binder/powder feedstocks, such as viscosity and strength have been studied. The viscosity of the binder as a function of temperature has b een determined by using a rotary viscome-ter. Penetration test has been done to obtain the strength of aqueous based binders with different compositions. The conditions of mixing of the binder with the Ti-6Al-4V powder, to obtain a uniformly mixed feedstock, have been also investigated. The quality of the mixing has been determined by using thermal analyses, and the critical powder loading has been determined. The properties of the feedstock with 50vol％ powder loading are also reported.
