【Abstract】 A scatheless method to measure the thickness of metallization layer on alumina ceramic through XRF was developed.The ingredients of metallization layer were analyzed qualitatively and quantitatively.Standard samples for measuring were designed and calibrated.Programs for scatheless measurement and corresponding adjustment methods were also established.The designed method is applicable and credible,according to the experimental results that the measurement error was less than 5% and the relative standard deviation was less than 2% within the measuring range from 12.66 μm to 87.02 μm.更多还原
