The thickness of the implanted layers increased by about an order of magnitude when the temperature was elevated from 100℃ to 400℃. Higher surface hardness was also obtained in the high temperature implantation. X-ray diffraction showed the presence of nitrides of tantalum and tungsten in the implanted surface.展开更多
文摘A Cemented Carbide material was implanted with dual nitrogen plus tantalum ions at temperatures of 100℃ and 400℃ and a dose of 8× 10^17 ions cm^-2. The thickness of the implanted layers increased by about an order of magnitude when the temperature was elevated from 100℃ to 400℃. Higher surface hardness was also obtained in the high temperature implantation. X-ray diffraction showed the presence of nitrides of tantalum and tungsten in the implanted surface.
