The investigation of production parameters of Ti-6Al-4V component by powder injection molding

Abstract: In this study, the optimized sintering parameters for a feedstock obtained by mixing the powder of Ti-6Al-7Nb and 31wt% binder system (comprised of high-density polyethylene, Polypropylene, PEG 20000, paraffin wax and stearic acid), were determined. In order to produce a component, Taguchi method was applied to obtain the optimum conditions. As a result of ANOVA, sintering temperature was proven to be the most effective one. It was also proven that for feedstock comprised of 69wt% Ti-6Al-7Nb powder, the suitab… Show more

“…To produce small-sized items with a complex configuration of titanium alloys, powder injection molding (PIM) method is well suited. Commonly, for PIM are used powders ranging in size from 10 to 100 μm or more, both spherical [1] and irregular [2] shaped. The metal powders selection to produce feedstock is critical for PIM method.…”

“…Due to the relatively low thermal conductivity (about 1/5 of iron) and Young's modulus (about half of iron) [5][6][7], the Ti-6Al-4V alloy is difficult to be processed by traditional methods, such as machining or forging. As one of the state-of-the-art advanced manufacturing technologies, metal injection molding (MIM) has become the major manufacturing technique for complex Ti-6Al-4V materials, with a relatively low-cost and near-net-shape process [8][9][10][11][12][13][14]. MIM combines the shape-making complexity of plastic injection molding with the material flexibility of powder metallurgy, which is composed of four sequential steps: mixing, injection molding, debinding, and sintering [15,16].…”

“…Ti-6Al-4V alloy has excellent corrosion resistance due to the formation of an oxide layer on its surface. Also, it is preferred especially in medical implant applications because of its good biocompatibility and biomechanical properties [6][7][8][9]. The porous structures are used to improve thermal insulation properties, reduce weights, noise, and vibration in automotive and aerospace industries, meet mechanical properties close to bone tissue and assist in osseointegration of medical implants [10].…”
