  1. The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film

    試驗結果表明:所選原料尺寸、形狀及度可滿足固體潤滑劑性能要求;聚四氟乙烯樹脂熱分解溫度超過400 ,但在ptfe中加入無機填料會使復合材料吸水率提高,熔融溫度及分解溫度降低,且伴有氧化分解反應;碳纖維表面含有c = o及c - o - c等極性基團,有利於提高其與其它組分相容性,提高層間剪切強度;均勻設計試驗方法能夠用較少試驗次數找出配方與摩擦性能間關系,擬合曲線基本能表示各配方摩擦系數發展趨勢;配方中不加銅粉或不加,其摩擦系數均較高,說明銅粉和應該配合使用;當銅粉15份、60份時,銅粉30份、30 - 40份時,銅粉60 、15 - 30份時,摩擦系數均具有較低值;聚四氟乙烯樹脂在空氣冷卻時結晶度大,磨損量也是三者中;同時,固體潤滑劑試樣在空氣冷卻時磨損量也是三者中:不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副,在金屬表面均可形成潤滑轉移膜,從而減少金屬摩擦副表面間直接接觸,大大延長其使用壽命;轉移膜中主要含有較多、少量聚四氟乙烯、 moo 。
  2. It was found that in the case of non - isothermal crystallization, the onset and maximum crystallization temperatures of the nylon 6 of the nanocomposites are increased, while the crystallinity and crystallization growth rate is reduced

    在非等溫條件下,尼龍6納米薄片復合體系結晶起始溫度以及大結晶速率時溫度均比尼龍6有明顯提高,但結晶度以及結晶速率卻出現下降。
  3. The results indicated that the electrochemical reversibility and charge / discharge efficiency on spectral pure graphite electrode are superior to that on the other two, and the possible causes of these differences are presented

    結果表明:其在光譜電極上電化學可逆性、充放電效率優,處理上次之,而在未處理表現不理想。
