利用熔渗工艺研制成功了具有平行孔的烧结型过滤器。用于熔渗的铜丝预先埋入铁基体中。与市售普通过滤器相比,这种过滤器具有较高的孔隙度、较底的过滤阻力又有较高的强度。前言利用一种特殊的粉末冶金工艺制成了高性能的多孔过滤器。这种方法可以在比较大的范围内调节过滤器的孔径和孔隙度。常规的生产方法有:球形粉末松装烧结,不规则粉 The use of infiltration process successfully developed with parallel hole sintered filter. The infiltrated copper wire is embedded in the iron base in advance. Compared with the ordinary filter on the market, this filter has a higher porosity, higher filtration resistance than the end of a higher strength. Preface The use of a special powder metallurgy process to create a high-performance porous filter. This method can be adjusted in a large range of filter pore size and porosity. Conventional methods of production are: loose spherical powder sintering, irregular powder
