The degrees of crystallinity of pure ptfe under the different conditions of water cooling, air cooling and furnace - varying cooling were made comparison by xrd. the thermal stability of pure ptfe and solid lubricant was analyzed by dsc - tg ; the composition and valence state of elements in the surface of carbon fiber, solid lubricant before and after friction test and lubricant transfer film were characterized by xps ; the frictional property of solid lubricant was tested by pin and disk test rig. the frictional wear property of solid lubricant between embedded bearing sleeve and steel axle friction pair ring was tested by special simulate test machine, the hardness of solid lubricant was tested by pm ; the compression strength of solid lubricant was tested by material test machine
用sem表徵原料微觀結構、摩擦表面及潤滑轉移膜表面形貌：用xrd進行原料物相分析，及比較水冷卻、空氣冷卻、隨爐冷卻三種工藝條件下的純聚四氟乙烯樹脂的結晶度；用dsc - tg分析純聚四氟乙烯樹脂及固體潤滑劑的熱穩定性；用xps表徵碳纖維表面、固體潤滑劑摩擦前後表面、潤滑轉移膜表面的元素組成、價態變化；用銷盤式摩擦磨損試驗機對固體潤滑劑進行摩擦性能測試；採用專用的臺架模擬試驗機對固體潤滑劑鑲嵌軸承套與鋼軸摩擦副間的摩擦磨損性能進行測定；用萊次偏光顯微鏡（ pm ）測試固體潤滑劑的硬度；用材料試驗機測試固體潤滑劑的抗壓強度等。 -
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：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；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的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：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的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。 -
