石英坩埚扁喷嘴的几何精度和表面光洁度是单辊法制取非晶态合金宽带成败的重要因素.这喷嘴是一条厚度为0.2～0.5毫米,宽度为2～4毫米的长窄缝.石英与光学玻璃性质较近,但比光学玻璃坚脆,组织不均,加工后孔的内壁易出现横向裂纹.在玻璃上加工异形孔的技术有:超声波法、内刃切片法及外圆切割法.也可用单色性好又能在一个狭小的区域内集中高能量的激光束来实现.
The geometric precision and surface finish of the quartz crucible flat nozzle is an important factor in the success or failure of the single-roll method for preparing broadband amorphous alloy.The nozzle is a long and narrow slit with a thickness of 0.2 to 0.5 mm and a width of 2 to 4 mm Quartz and optics The properties of the glass are relatively close, but it is more brittle than the optical glass and has uneven structure, and the inner wall of the hole is easy to appear transverse crack after processing. Techniques for processing irregular holes in glass include: ultrasonic method, inner edge slice method and cylindrical cutting method. Available monochromatic good but also in a narrow area concentrated high-energy laser beam to achieve.
