A Technique for the Determination of Cobalt in Tungsten Carbide Bits by Means of X-ray Fluorescence Spectroscopy

Volume 19, Number 6 (Nov. 1965) Page 193-193

Wybenga, F.T.


It has been shown by the use of microscopic techniques (1-3) that cemented tungsten carbide bits prepared by vacuum sintering have very inhomogeneous surfaces. This inhomogeneity can be a serious obstacle when using x-ray fluorescence techniques for analysis of these materials.
