摘要：

Extremely strong and wear-resistant surfaces of AISI 304 and 310 stainless steels have been produced by rapid, high-dose nitrogen ion implantation at elevated temperatures. X-ray diffraction, conversion electron Mössbauer spectroscopy, and Auger electron spectroscopy reveal that this behavior is due to thick layers (> 1 μm) of austenite which contain as much as 20 at% N in solid solution after implantation of 2 × 1018 N atoms/cm2 into samples held near 400°C. Much larger retained doses are obtained at the elevated temperatures. © 1990.
