Abstract The injection moulding of metal powder is one of the newest processes for producing titanium components. In this research, challenges of fabrication titanium component by low- pressure powder injection moulding (LPIM) were studied. A hydride-dehydride titanium powder was kneaded with paraffin wax based binder system in 53 vol% powder loading. Powder-binder was injection moulded using low pressure injection moulding machine to prepare the green part. This process was followed by debinding and sintering. The injection results showed that feedstock with high powder loading was not appropriate for LPIM. The suitable parameters of solvent debinding were obtained from soaking the samples in n-hexane at 60 °C temperature. The open channels were observed in solvent debound components which can help remove the binder in subsequent stages. The hardness and density of the sintered part were 490 HV and 4.11 g/cm3, respectively. Coarse α plates and α/β colonies were observed in the microstructure.

氢化-脱氢钛粉低压粉末注射成型制备钛部件

摘要 金属粉末注射成型是生产钛部件的最新工艺之一。在这项研究中，研究了通过低压粉末注射成型 (LPIM) 制造钛部件的挑战。将氢化物-脱氢钛粉末与石蜡基粘合剂系统以 53 vol% 的粉末负载量捏合。使用低压注塑机对粉末粘合剂进行注塑以制备生坯。该过程之后是脱脂和烧结。注射结果表明，高粉末负载的原料不适用于 LPIM。通过将样品在 60 °C 的温度下浸泡在正己烷中获得合适的溶剂脱脂参数。在溶剂脱脂组分中观察到开放通道，这有助于在后续阶段去除粘合剂。烧结件的硬度和密度分别为 490 HV 和 4.11 g/cm3。在微观结构中观察到粗糙的α板和α/β菌落。
