一种轮对光整加工用中性电解液
本专利技术涉及一种中性电解液,特别涉及激一种轮对光整加工用中性电解液,属于光化学
技术介绍
通常轮对是做旋转滚动,且承载着运载车辆的全部重量,因此在运行过程中很容易出现磨损。常规轮对的制造工序为:车轮坯件锻造→粗车外圆→精车外圆及内孔径→中频淬火、回火下料→修研中心孔→磨外圆→铣键槽。热处理虽然可以改变材料组织性能,但容易引起轻微的塑性变形。中频淬火、回火难以提高轮对的显微硬度和耐磨效果。粗磨、半精磨、精磨是磨削轮对最普遍的加工工序,由于精磨时磨削速度很高,磨削区瞬时温度也很高,容易产生表面烧伤和磨削裂纹,因此很难保证轮对外圆磨削到很低的表面粗糙度,轮对表面粗糙度若大,应力集中就强,会大大降低轮对的疲劳强度。此外,由于磨削工作量大,磨削加工时会产生大量油雾或水雾,对环境造成污染,对工人健康造成损害。因此上述工序存在轮对显微硬度小、耐磨性差、表面粗糙度大、生产周期长、环境污染严重等问题。
