直接烧结 meaning in Chinese
direct sintering
Examples
- ( 4 ) some required - shape metal parts with certain mechanical strength are sintered successfully with powerful laser
( 4 )采用大功率激光直接烧结镍基高温合金粉末,成形具有一定形状和强度的金属块体或零件。 - ( 3 ) there are many flaws in direct laser metal sintering , such as the high remnants stress , micro - hole and micro - crack in sintering parts . in order to solving those problems , the programming of scanning paths is put forward , and several parts are prepared with different scanning paths respectively . the following conclusion is educed : the parts produced with short - side scanning path and same scanning direction have the minimum structure , the rigidity of parts prepared by short - side and same direction scanning path is highest , and the density of parts produced with the vertical scanning path is maximal
( 3 )针对采用大功率激光直接烧结镍基高温合金成形金属零件存在的问题,如较大的残余应力,制件中存在着微裂纹、微孔洞等缺陷,初步提出扫描路径的规划,并采用几种不同的扫描方式进行烧结试验,发现采用短边扫描路径和同向扫描能够获得更加细小和分布均匀的组织结构,采用短边同向路径制备的试样其显微硬度最高,而采用变向扫描(垂直)路径制备的试样致密性最好。 - In this paper , a series of experiments are carried out with dlms for nickel - based metal powder materials , and the effect of process parameters in sample quality was investigated and analyzed . the main works are as following : ( 1 ) the effect mechanism of laser in metal powder and the nucleation mechanism are analyzed . ( 2 ) the process parameters that affect the quality of sintering parts are investigated and the way how they affect is clear
