molten test sample
解釋
熔體試樣-
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
本文對激光立體成形的工藝特性進行了深入系統的研究,發現如果要獲得理想的成形效果,就必須對成形過程中的工藝參數進行精密控制,例如激光功率、激光光斑大小、光束掃描速度、搭接率等;同時為了保證成形件有較高的尺寸精度和表面質量,必須對成形零件的氧化問題進行控制,通過改進側向送粉噴嘴的結構設計,成形件的表面氧化問題得到適度控制。
