The diffusion constants of O2, N2, H2, and Ar at 24 °C in H2O are calculated from interferometric data. The question of surface resistance to diffusion of O2 into water is discussed. There appears to be no such resistance.

Equal Thickness

Small contact angles, such as water on glass, have been shown to be measurable interferometrically using fringes of equal thickness after the fashion of Newton's rings. The measured angle for the water on glass system was 0.049 ± 0.006 degrees of arc.

Abstract A laser interferometric method of detecting holidays in and evaluating the corrosion protection of epoxy primer or other coatings was tested in the well known system Zn/ZnSO4/Zn. An electrochemical potential in the general range of corrosion couple values was applied, first to uncoated electrodes, then to coated anodes with measured, prepared holidays. The method is shown to give easily interpretable, visually obvious qualitative results. General methods of calculating good relative values and less accurate true values of corrosion currents are evolved.
