coarse spray
解釋
粗糙噴筆-
But the alloys fabricated by normal ingot metallurgy worsen the mechanical properties due to the coarse block - like or plate - like angular primary si particles. multi - layer spray deposit ( mlsd ) technology is a kind of rapid solidification with high cooling velocity up to 1 04 - 1 06k / sec, which can improve the microstructure, lessen segregation and increase the solid - solution of the alloy
利用多層噴射沉積技術的高冷速(可達10 ~ 4k / s ) ,可顯著改善al - si合金的顯微組織、減少偏析、提高合金固溶度等,使合金性能得以大幅度提高,擴大其應用范圍。
