Advancement in tungsten coating method is needed from both sides of plasma physics and material engineering in development of nuclear fusion reactor. It was discussed including an examination of fundamental parameters for membrane production, an examination about high-speed particle spraying, and possibility of the control utilizing an electric field. And the applicability of adhesion measurement using a laser shock spallation method was shown.

核聚变反应堆的发展需要从等离子体物理和材料工程两个方面来推进钨涂层方法的发展。讨论了制膜的基本参数检测、高速粒子喷涂的检测以及利用电场进行控制的可能性。说明了用激光冲击散裂方法测量附着力的可行性。
