Nanometer Wear Measurement by Ultra-Thin Surface Layer Activation

这项研究的目的是开发一种在线磨损测量系统，该系统可以监测从先前激活的表面层中逸出的伽马射线。第一阶段的研究已经确定了几种可行的方法来产生激活深度，这将允许准确和精确的磨损测量方案。第二阶段研究的目的是确定最可行的技术，并解决重复性、测量的实际准确性和校准等问题。

The objective of this study is to develop an in situ wear measurement system which monitors the gamma rays escaping from a previously activated surface layer. Phase I of the research has identified several feasible methods for producing activation depths which would allow an accurate and precise wear measurement scheme. The purpose of the Phase II research is to determine the most feasible technique and to address the issues of reproducibility, the actual accuracy of the measurement, and calibration.
