摘要：
Three types of nuclear reaction have been applied to study chromium conversion coatings on zinc electroplate. The 1005kev resonance in the **5**2Cr(p, gamma )**5**3Mn reaction has been used to determine the depth versus concentration profile of chromium in the coatings, while the **1**5O(d, alpha )**1**4N reaction has been used to profile oxygen content. alpha particle induced elastic forward scattering of protons (proton recoil) was used to determine the hydrogen profile. The results suggest that the newly introduced trivalent type treatments produce coatings containing water/hydroxide contents comparable to established hexavalent treatments.
