(一)实验方法 1.将试样(铝基体上有氧化膜的铝板)放在中间悬空的两块同样水平的台子上,在悬空处用切刀往下锤,将铝板试样从悬空处折断。如图1所示。 2.将折断后的试样加工成直线状,但不必将两半切开,并将不包括断面氧化膜的部分用清洁胶带粘住,只让包括断面氧化膜的部分进行复型,如图2所示。 (A) Experimental Method 1. The sample (aluminum substrate with an oxide film of aluminum) on the middle of the two suspended in the same level of the table, in the vacant with a knife down hammer, the aluminum sample from the dangling Break. As shown in Figure 1. 2. The broken sample processed into a straight line, but do not have to cut the two halves, and will not include the cross-section of the oxide film with a piece of adhesive tape, leaving only the cross-section of the oxide film of the complex shape, as shown 2 shows.
