目前碳复型的制备比较复杂且容易失真,尤其是定位或定点复型,其失败的几率就更大。我们在实践中摸索了一种比较简易的方法,可得到完整、清晰的碳膜。其制备的方法如下:(1)将金相试样用AC纸(塑料薄膜)复膜下来,放在真空镀膜台中喷镀铬及碳;(2)把制得的二次碳复型剪成φ3mm铜网大小的方块,然后把它放在铜网上,将其碳膜一侧朝上,利用铜网上的醋酸甲脂,使AC纸与铜网粘在一起;(3)铜网把放在垫有海棉、盛有醋酸甲脂的培养皿里,
At present, the preparation of carbon compound is more complex and easily distorted, especially the positioning or fixed-point compound, the chance of failure is even greater. In practice, we explored a simpler method to get a complete and clear carbon film. The preparation method is as follows: (1) The metallographic sample is coated with AC paper (plastic film), and placed in a vacuum coating station to spray chromium and carbon; (2) the obtained carbon double cut is cut into φ3mm The size of the copper mesh box, and then put it on the copper network, the carbon membrane side up, the use of acetate copper acetate network, so that AC paper and copper network glued together; (3) put the copper mesh There are sponges, petri dishes filled with acetate,
