Embodiment Construction
[0022] The method for testing the bonding strength of the stainless steel back tube and the high-purity copper target of the present invention is as follows:
[0023] First, select an externally threaded 316L stainless steel back pipe with a diameter of 25mm and a length of 50mm, such as figure 1 shown;
[0024] Then, use a grinder to do flat surface treatment on the sprayed surface of the external thread 316L stainless steel back pipe, so that the sprayed surface is formed into a smooth surface, and the circular runout does not exceed 0.5mm, such as figure 1 As shown, the sprayed surface is one end surface of the stainless steel back pipe;
[0025] Next, use acetone to degrease the externally threaded 316L stainless steel back pipe, and use ultrasonic waves to wash with alcohol. The alcohol should soak the entire externally threaded 316L stainless steel back pipe. , the drying temperature is 100°C, and the drying time is 40 minutes. During the drying process, the sprayed su...
