镶嵌复合材料的生产工艺

Manufacture of inlay clad strip

镶嵌复合材料是通过可控气氛热复合技术制造出来的新型材料.复合前对覆层材料进行预处理和复合后的扩散退火对复合材料强度的影响较大.开槽精度对成品分条定位有直接影响,一般公差为±0.10mm可保证成品的精度.

Inlay clad strip is a new material manufactured through controllable atmosphere heat bounding technology. It＇s of great signification for saving noble metal. Through experiments and mass production, this article studies technology and process such as cladding material preparing, surface-treating to compounding face, controllable atmosphere heat bounding, precision controlling etc. and selects model of equipments and tools with high precision. Study result shows that selection of inlay clad strip should be decided base on environment factors such as working current etc. Pre-treatment before bounding and material soft/hard status greatly influents the compounding strength. Strip shape of clad material and groove-cutting precision directly relates to orientation and slit of finish product. Increasing orientation variation should be considered according to the widen feature of different type of clad material during technical and process design.
