由日本岛根县工业中心和岛根大学等单位组成的财团正在实施等离子体对钢表面渗碳的研究开发，已获得初步成功，并在１９９９年中建工业试验装置以争取尽快实用化。该技术为通过对钢材表面渗碳使之提高强度，而内部仍然保持良好韧性的表面渗碳技术。它利用高温的等离子体炉对钢?
The consortium comprising Japan’s Shimane Prefecture Industrial Center and Shimane University is carrying out plasma research on the carburizing of steel surfaces and has achieved initial success. In 1999, it built a pilot plant for industrialization as soon as practicable. This technique is a surface carburizing technique that maintains the toughness internally by carburizing the steel surface to increase its strength. It uses high-temperature plasma furnace steel?
