INTERACTION OF OXIDE FILM WITH MOLTEN FLUX DURING ALUMINUM BRAZING

金属学报(英文版)

The interaction of oxide film with molten flux during aluminum brazing has been studied by means of X-ray powder diffraction. The following conclusions have been deduced: The swell- ing of aluminum oxide film is caused by Li~+ inserting into the vacancies of octahedral or tetrahedral structure of 0 atom skeleton in у-Al_2O_3 . The strength of oxide film decreases as the crytallinity increases by the treating of flux containing LiF.

用X射线粉末衍射法研究了铝氧化膜与熔盐钎剂的作用行为。结论指出:铝钎焊过程中铝氧化膜的溶胀是由于钎剂中的Li~+挤入氧化膜γ-Al_2O_3氧骨架中八面体或四面体空隙,从而撑大了氧骨架所致;含F-钎剂作用γ-Al_2O_3后,显著提高了它的结晶度,导致膜强度的下降并易被破坏。
