Abstract Based on X-ray photoelectron spectroscopy technique,the National Institute of Metrology of China developed an accurate analytical method and took part in the CCQM-K67 international key comparison on surface analysis measurement of the composition for Fe-Ni alloy film.According to the recently published comparison results, the measured Fe atom fraction (51.48%) by the National Institute of Metrology of China was agreed with the reference value (50.02%) of the CCQM-K67 key comparison.
