采用改进的MPV-1500型摩擦磨损试验机,国内首次研究了直流磁场对抗磁性(锌黄铜)和顺磁性(铝合金)材料互配副干摩擦学特性的影响.结果表明:磁场的施加和增大,加剧了抗磁性锌黄铜的磨损,降低了顺磁性铝合金的磨损,互配副的摩擦系数均有增大趋势;在抗磁性锌黄铜背面添置铁磁性材料,即可克服磁场对锌黄铜干摩擦学特性的不利影响;销、环试样的化学性能以及装卡装置的磁性均可能影响试验研究结果.
The effect of DC magnetic field on the tribological properties of the interlaced dry-bonded tribological materials with different magnetic (zinc-brass) and paramagnetic (aluminum alloy) materials was investigated for the first time using the improved MPV-1500 friction and wear tester. Large, aggravating the wear of the anti-magnetic zinc brass, reducing the wear of paramagnetic aluminum alloy, the friction coefficient of each other pairs have an increasing trend; magnetic anti-magnetic zinc on the back of the addition of ferromagnetic materials, you can overcome the magnetic field Zinc Brass dry tribology characteristics of the adverse effects; pin, ring the chemical properties of the sample loading device and the magnetism may affect the experimental results.
