Abstract

Do two different and independent methods of estimating the wear rate of a test sample yield the same numerical result? Numerical values of specific wear rates estimated on the basis of alternative methods using a set of dry sliding rotary-pin-on-disk experiments are presented. Wear rates of brass and aluminium alloy pins were estimated using gravimetric and wear scar area methods. Gravimetric and linear displacement methods were used to assess wear rates of ABS plastic and machinable wax pins. Scepticism about the estimated nominal values of wear rates is reduced when alternative assessment methods result in comparable numerical values, or values having the same order of magnitude. This is particularly useful when ranking competing materials for wear rates, when the differences in these rates are small. Uncertainties in individual test sample wear rates, and dispersion in the nominal values of wear rates are also computed to support the aforementioned observations.

论使用替代测量方法估算旋转销盘摩擦磨损率
估算测试样本磨损率的两种不同且独立的方法是否会产生相同的数值结果?本文介绍了利用一组干式盘上滑动旋转销实验,根据不同方法估算出的具体磨损率数值。使用重力法和磨损痕面积法估算了黄铜和铝合金销钉的磨损率。重力法和线性位移法用于评估 ABS 塑料和可加工蜡销的磨损率。当其他评估方法得出可比数值或具有相同数量级的数值时,对磨损率估计标称值的怀疑就会减少。在对磨损率差异较小的竞争材料进行排名时,这一点尤其有用。此外,还计算了单个测试样本磨损率的不确定性和磨损率标称值的分散性,以支持上述观察结果。
