9414459 Wilbur The effects on tribological performance of high density ion implantation at low energies of oxygen, carbon, boron and nitrogen into tool steels will be studied. The research is a cooperative effort which involves the Colorado State University, the Physical Technical Institute in Minsk, Belarus, and Hughes Company Research Laboratories. The dose and implantation conditions which induce maximum resistance to sliding wear in commercial tool steels will be identified, and the mechanisms of deep diffusion at high implantation rates will be studied. Tribological test results will be compared with microstructural and surface analytical results obtained by a number of complementary techniques. ***

9414459研究低能量氧、碳、硼、氮高密度离子注入工具钢对摩擦学性能的影响。这项研究是科罗拉多州立大学、白俄罗斯明斯克物理技术研究所和休斯公司研究实验室的合作成果。将确定在商业工具钢中引起最大抗滑磨性的剂量和注入条件，并将研究在高注入速率下的深扩散机制。摩擦学测试结果将与通过一些补充技术获得的微观结构和表面分析结果进行比较。***
