The theoretical Khare model modified by Y Kumar et al. [J. At. Mol. Sci. (2012)], has been used to calculate the total cross sections for K-shell ionization of two targets, chromium, and cobalt, (i.e., Cr & Co) due to electron impact at incident electron kinetic energy from ionization threshold energy to 1 GeV. This method is based on plane wave Born approximation. The present model requires only two atomic parameters, ionization energy, and atomic number. The calculated cross sections have been compared with the available experimental data and other theoretical cross sections. The present calculated cross sections are in excellent agreement with measured by Liovet et al. [J. Phys.B 33, 2000] and Hoffmann et al. [Z. Phys. Rev. A 22, 1980] for Cr. A good agreement is found between the present calculations and measured An et al. [Chin. Phy. Lett. 18, 2001] and Se et al. [Phys. Lett. 29, 1974]
