用铸造法制备含弥散分布石墨粒子的铝合金复合材料,日益引起人们的注意并趋于实用化。 本文是在半固态法和漩涡法基础上发展出一种半固态漩涡搅拌法。它利用半固态料浆的较高粘度和搅拌漩涡,使不浸润的石墨粒子加入并保留在铝合金料浆中,从而制备出含石墨粒子的铝合金复台材料。 一、实验方法 制备石墨铝复合料浆的装置如图1所示。 设备由搅拌器、坩埚和炉体三部份组成。搅拌器由不锈钢制成,叶片表面施加喷涂氧
The casting method for the preparation of dispersion distribution of graphite particles containing aluminum alloy composite materials, has drawn increasing attention and has become more practical. This article is based on the semi-solid method and the vortex method developed a semi-solid vortex stirring method. It makes use of the higher viscosity and stirring vortex of semi-solid slurry to make non-wetting graphite particles join and remain in the aluminum alloy slurry, so as to prepare the aluminum alloy composite material containing graphite particles. First, the experimental method Preparation of graphite aluminum composite slurry device shown in Figure 1. Equipment from the blender, crucible and furnace body composed of three parts. The stirrer is made of stainless steel and the surface of the blade is sprayed with oxygen
