Titanium 6-aluminum 4-vandium alloys were etched for varying periods of time in aqueous solution of hydrofluoric acid and ammonium dihydrogen phosphate. Following etching, one-half of the specimens were covered with vacuum evaporated gold while the o

When the excitation energy lies near the ionization potential of many core electrons, core-hole relaxation effects strongly affect x-ray emissions. Under near-threshold electron excitation of the cerium 4d subshell both the incident electron and a 4d

We have obtained soft x-ray appearance potential spectra of the N and M levels of samarium metal by scanning the electron excitation energy from 50 through 1560 eV. Newly observed line-like x-ray emission singularities are identified for excitation e

Evaporated aluminium on Ti-6 wt% Al-4 wt% V alloy was anodized in phosphoric acid and other electrolytes. The anodic oxide formed was characterized by various techniques and it was found that a duplex oxide forms in which titanium has diffused throug

The work function of impregnated tungsten dispenser cathodes can be lowered by several tenths of an electron volt by sputter coating the emitting surface with an 80% Os, 20% Ru coating approximately 0.5 μ thick. The lower work function would be expe

Frequently it is not easy using visual or even microscopic examination of an adhesive joint to determine after physical testing whether an apparent adhesive failure occurred at the original interface due to improper wetting or at some new interface l
