powder nozzle meaning in English
干粉喷嘴
Examples
- Powder flame spray and spray fusig gun , with various powder nozzles attached , can do spray coating with fine metallic powder and ceramic powder
粉末火焰喷涂喷焊设备，配有各种粉末喷嘴，能喷涂金属微细粉末和氧化物涂层。 - The results showed that the processing parameters ( such as laser power , the diameter of laser , scanning speed of laser beam , ratio of overlapping ) are important to acquire a perfect component . furthermore , in order to assure geometric properties ( accuracy , surface finish ) , the structure of the off - axial powder nozzle was improved to avoid the oxidation of the molten pool . the density metal test sample of rene95 high - temperature alloy was made by lsf through optimizing the processing parameters
本文对激光立体成形的工艺特性进行了深入系统的研究，发现如果要获得理想的成形效果，就必须对成形过程中的工艺参数进行精密控制，例如激光功率、激光光斑大小、光束扫描速度、搭接率等；同时为了保证成形件有较高的尺寸精度和表面质量，必须对成形零件的氧化问题进行控制，通过改进侧向送粉喷嘴的结构设计，成形件的表面氧化问题得到适度控制。
