电脉冲消除堆焊复合耐磨衬板

   耐磨堆焊设备本文通过分析75小时球磨产物经900℃退火后的相组成,并结合Miedema理论模型的热力学分析和晶体学分析,提出Ni31Si12属于一种亚稳相;同时,本文认为75小时双金属耐磨复合钢板上海11选5开奖结果球磨产物严格而言应属于一种具有较高能量的亚稳定“Ni3Si型无序化合物”,这与有些研究者认为该物相属于Ni基“过饱和固溶体”的观点有一定的区别。

   为了研究电脉冲消除金属材料堆焊复合耐磨衬板上海11选5开奖结果内部残余应力的效果,通过储能电容器放电产生高能电脉冲,对淬火后的45优质碳素结构钢冷轧薄板件进行放电处理,采用小孔法测定电脉冲处理前后试样内残余应力的变化规律.用于电脉冲处理的脉冲电流为指数衰减的振荡波形,同时满足第一个主峰的电流密度为12.2kA/mm2,单次处理的振荡脉冲持续时间小于0.8ms.试验结果表明,经过电脉冲处理后,堆焊复合耐磨衬板淬火件中2个主方向残余应力的幅值均出现较为显著的降低,且两者都出现均化效果.
