Description

technical field

[0001] The invention belongs to the technical field of sample preparation equipment manufacturing, and in particular provides a convenient and practical double-spray electrolytic thinning instrument for transmission electron microscope samples, which is a new complete set of equipment suitable for manufacturing transmission electron microscope experiment materials. Background technique:

[0002] At present, in most colleges and research institutes in my country, most of the electrolytic double-spray instruments used to make TEM samples are domestically produced, and the main one is the MTP-1 electrolytic double-spray sample preparation instrument of Shanghai Jiaotong University, such as figure 1 As shown, there are the following disadvantages: (1) Compared with foreign countries, the electrolytic polishing current range is narrower (0-15mA range), and the corresponding parameters of foreign equipment are generally an order of magnitude higher (0-400mA range). ...
