Surface Durability of Ion-Nitrided Rollers.

Breaking-in Mechanism of the Sliding Surface in a Hermetic Rotary Compressor Employing an Ion-Nitrided Crankshaft

LOW-ENERGY-ION ENHANCED DIFFUSION AT THE SURFACE OF METALS

Radiation enhanced diffusion at the surface of metals has been observed and studied for low-energy nitrogen ions at the surface of copper. The displacement of the target atoms during irradiation creates vacancies and other defects near the surface, thus enhancing the diffusion of implanted materials toward the surface and also into the solid. The mechanism has been studied here by a specia...

Measurements of Shallow Water Breaking Wave Rollers

Large scale laboratory experiments concerning breaking wave propagation over a fixed-bed, barred beach were performed. The primary observations of interest were video intensity time series obtained from a set of high-resolution video cameras in order to study the onset of wave breaking in shallow water and wave roller transformation in the surf zone. The approach is new in the sense that the an...

SURFACE SCIENCE LETTERS INTERACTION OF Hz AND CO WITH CARBIDED AND NITRIDED Ni(lOO)

In our previous paper [I] we reported that the presence of P, S and Cl adatoms on Ni(lO0) surface causes a reduction of CO and Hz adsorption rate and adsorption binding energy. In the case of Cl and S the observed poisoning effect is stronger than the predicted one by a simple adsorption site blocking model and it increases in the sequence P, S, Cl. Since Cl, S and P have similar atomic radii w...
