關(guān)于材料磨損率的問題 W=V/(S×L)如何理解 詳細(xì)大家點進(jìn)來
|
|
我看到一篇文獻(xiàn)中是這樣說明的 這是一個磨損實驗 UMT-3MT tribometer (CETR, USA) was used in order to evaluate the friction and wear characteristics of the sliding couples. A sliding speed of 300 rpm, a constant normal load of 5 N and a sliding stroke of 5 mm were used in the experiments and the friction coefficient was continuously recorded during testing. Based on the wear track depth profiles detected by Alpha-Step IQ profilometer, the wear losses of the coatings V can be obtained after the sliding tests were completed. Then according to classical wear equation, the wear rate W can be calculated by the following equation: W=V/(S×L) where S is the sliding distance and L is the normal load applied 我想請教大家V是代表的被磨損材料的體積么?那么最后W的單位制是長度平方/力,即m×m/N,這代表什么意義呢?希望大家為小弟解答解答 |
