摘要

对于Ga/In/Sn, Ga/In/Zn和Ga/In/Sn/Zn的共晶，报告了室温下粘度和电阻率的测量。对于使用这些流体作为润滑剂的倾斜垫片，计算接触阻力、摩擦和薄膜厚度。在环空中，磁流体动力能量耗散的相对大小是根据一个优点值，即哈特曼数来讨论的。实验结果表明，镓合金表现出最有利的特性。

Properties and performance of gallium alloys in sliding contacts

For eutectics of Ga/In/Sn, Ga/In/Zn, and Ga/In/Sn/Zn, room-temperature measurements are reported for viscosity and resistivity. Contact resistance, friction, and film thickness are calculated for tilted pads using these fluids as lubricants. Relative magnitudes of magnetohydrodynamic energy dissipation in an annulus is discussed in terms of a figure of merit, namely, the Hartmann number. The experimental findings show that the gallium alloys display the most favorable characteristics.<>
