85年12月份在国内首次研究出金属陶瓷结构的氩离子激光器。但是长度一米、内径均匀、直线性好的气密95氧化铝陶瓷管,国内至今仍不能生产。我们经大量调研和反复试验,用内径经过研磨的100毫米长的95氧化铝管,采用分段焊接法,初步制成金属陶瓷结构氩离子激光器用的长陶瓷管。具体焊接工艺流程如下:1.将内径研磨加工(误差<±0.1毫米),长度为100毫米的95氧化铝管两端采用高温钼锰法进行金属化处理;2.在金属化层上电镀4微米的镍膜;3.在950～1000℃的干氢中烧结20分钟,使镍膜与金属化层之间结合牢固;
85 years in December for the first time in China to study the structure of the cermet argon ion laser. But the length of one meter, uniform diameter, good linearity airtight 95 alumina ceramic tube, the domestic still can not produce. After a lot of research and trial and error, we used the 100mm long 95-diameter alumina tube with the inner diameter to make the long ceramic tube for the cermet-structure argon-ion laser by the segmented welding method. The specific welding process is as follows: 1. The inner diameter of the grinding process (error <± 0.1 mm), a length of 100 mm at both ends of the 95 alumina tube metallization treatment using high temperature molybdenum manganese method; 2 plating on the metallization layer 4 Micron nickel film; 3. Sintering at 950 ~ 1000 ℃ dry hydrogen for 20 minutes, the nickel film and the metal layer between the firm;
