据苏《自然》84年7号报道:虽然对离子束焊接的物理和技术特性不久前才开始加紧研究,但初步的成果已经表明,用这种方法能在焊接过程中形成合金焊缝。例如,用离子束加工不锈钢,在焊缝中能成功地引入大于1%的钽,从而大大地改善了焊缝的质量。用这种方法焊接时,从气体放电区向真空扩散的等离子体,在强磁场作用下,向被焊接的材料表面 According to Su “Nature” 84, reported on July 7: Although the physical and technical characteristics of ion beam welding began to intensify the study not long ago, but preliminary results have shown that the use of this method can be formed during the welding alloy weld. For example, the use of ion beam machining of stainless steel, the weld can be successfully introduced more than 1% of tantalum, which greatly improved the quality of the weld. When welding in this way, the plasma diffused from the gas discharge zone to the vacuum is forced by the strong magnetic field toward the surface of the material to be welded
