數控加工基礎——數控加工的特點和優勢 1、適應性強、靈活性高CNC加工工藝適用于種類繁多的零部件制造，新的CNC加工零件可以用新程序生產，無需更換機器和控制器。 2、高精度、高品質的數控機床按照CAM指令進行加工，杜絕了人工干預造成的誤差。將進行多次測量以確保零件的高精度和剛性、尺寸精度。CNC機床的加工精……
真空擴散焊的作用
2022-04-11
擴散焊是一種固態連接工藝，適用于相似和不同的材料，主要是金屬，盡管陶瓷材料也可以使用這種工藝進行連接。該過程通過原子在高溫下穿過接頭界面的擴散而起作用。擴散結合不需要任何填充材料，對于類似材料的接頭，它是完全自生的。當擴散結合不同材料時，可以使用中間層。 典型的商用擴散焊接爐是真空爐，配備液壓柱塞，通過石墨工具向……

擴散現象的數學描述 ? Fick第一定律 在擴散過程中，各處的濃度C只隨距離X變化，而不隨時間t變 化，即?C/?t＝0，此時的擴散稱之為穩態擴散。在穩態擴散過 程中，通過某一截面的擴散流量J與垂直與此截面方向上的濃 度梯度?C/?X成正比，其方向與濃度降低的方向一致，寫成公 式為: 此式即為一維條件下Fick第一定律……
