中文摘要:
      本文研究了AgSnO2电触头材料的二步烧结工艺。通过讨论预烧温度、预烧时间和升温速率对AgSnO2电触头材料性能的影响, 确定了最佳的预烧温度和时间为700℃?.5h, 最佳升温速率是预烧前15K/min, 预烧后3K/min。对二步烧结工艺与常用一次烧结工艺制备的AgSnO2电触头材料的性能与显微组织进行了比较,结果表明:二步煅烧工艺提高了AgSnO2粉体烧结活性,促进了粉末在高温烧结阶段的致密化,最终大大改善了AgSnO2烧坯的显微组织,提高了其性能。

英文摘要:
      The Two-Step Sintering processed of AgSnO2 electric contact materials was studied. By the discussion for the effect of pre-sintering temperature, pre-sintering time and heating rate on the properties of AgSnO2 electric contact materials, we confirm the optimal pre-sintering temperature and pre-sintering time are 700℃ for 0.5h and the beat heating rate are 15K per minute before pre-sintering and 3K per minute after pre-sintering. By the comparative study on properties and microstructures of AgSnO2 electric contact materials prepared by two step sintering process and the traditional one-step sintering process, The results indicate that two-step sintering processed AgSnO2 electric contact material possesses improved sintering activity of AgSnO2 power and promotes its densification in the high-temperature-sintering stage which eventually improved the microstructure and performance of AgSnO2 electric contact materials.
