Hello dear all of you researchers,
How can I calculate or determine the exact 'P' content of the coating of electroless Ni-P deposition on the materials?
I look forward to hearing from you and thanks all for your answers in advance.
It is best to analyze the cross-section of Ni-P coating using SEM/EDX. An EDX mapping of the cut already brings the phosphorus content with an accuracy of approx. 1%. The second option is the image analysis of the entire cross-section (SEM image with a good resolution and increased contrast): surface of the dark (black) phase corresponds to the volumetric phosphorus content. Image analysis can provide better than 1% accuracy. The volumetric fractions can be converted into mass fractions with the aid of known phase densities.
Thank you so much Mr. Vadim Verlotski. Could you suggest any reference about this? So, I can investigate thoroughly.
Best regards.
You may try XPS otherwise known as ESCA-electron spectroscopy for chemical analysis. RBS as well may yield some information
