This paper presents the results of using an aqueous milling media in comparison with traditional milling routes, as well as the influence of the milling media interaction with powder on the morphology and agglomeration behaviour. Hard Metal powders were milled in four milling media, two of them consisting of traditional milling routes and two of them aqueous routes. The aqueous milled powder is larger in size, similar to acetone and exhibits higher hardness as compared to the powder milled using isohexane, acetone, thus lowering the pressability. The pH adjustment of the water leads to soft agglomerates similar to isohexane and acetone. Powder oxidation occurs after the drying process, being more intense in the case of using an aqueous medium. Using N₂ atmosphere has inhibited the powder oxidation for the powder milled in traditional media. Using CO₂ or by gradual exposure to air the spontaneous oxidation is prevented for aqueous processing.

本文介绍了与传统的研磨路线相比使用水性研磨介质的结果，以及研磨介质与粉末的相互作用对形态和团聚行为的影响。硬质金属粉末在四种研磨介质中进行研磨，其中两种由传统研磨路径组成，而其中两种则为水性路径。与使用异己烷，丙酮研磨的粉末相比，该含水研磨粉末的尺寸较大，类似于丙酮，并且显示出较高的硬度，因此降低了可压制性。调节水的pH值会产生类似于异己烷和丙酮的软附聚物。粉末氧化在干燥过程之后发生，在使用水性介质的情况下更强烈。使用N ₂气氛抑制了传统介质中研磨的粉末的氧化。使用CO ₂或逐渐暴露在空气中可防止水处理的自发氧化。
