Segregation at the surfaces of CuxPd1− x alloys in the presence of adsorbed S
a r t i c l e i n f o The influence of adsorbed S on surface segregation in Cu x Pd 1 − x alloys (S/Cu x Pd 1 − x) was characterized over a wide range of bulk alloy compositions (x = 0.05 to 0.95) using high-throughput Composition Spread Alloy Film (CSAF) sample libraries. Top-surface and near-surface compositions of the CSAFs were measured as functions of bulk Cu composition, x, and temperatur...
متن کاملSurface Characterization and Tribological Behaviour of Ti-Ni-P Intermetallic Coatings on Titanium Alloys
In this research, tribological behavior of Ti-Ni-P intermetallic coatings on titanium substrates have been investigated under dry reciprocating conditions. Hardness profile testing results exhibit that high surface hardness has been attained and static indentation result shows that the intermetallic coating has better adhesion strength than the conventional ceramic coatings. In this respect, th...
متن کاملEnergetics driving the short-range order in CuxPd1-x/Ru(0001) monolayer surface alloys.
The energetics determining the distinct short-range order in two-dimensional (2D) monolayer Cu(x)Pd(1-x) surface alloys on a Ru(0001) substrate were investigated by Monte Carlo simulations and density functional theory calculations. Using a 2D lattice gas Hamiltonian based on effective pair interaction (EPI) parameters, the EPIs were derived for different Cu concentrations with Monte Carlo (MC)...

متن کاملSurface Properties and Concentration Fluctuations in Sn-based Molten Alloys
A simple model based on the concept of a layered structure near the interface has been used to investigate the surface tension and surface segregation of SnPb and SnZn molten alloys. With increasing concentration of Sn, the surface tension (a) of SnPb alloys has been found to increase, while a of SnZn alloys decreases, a of both systems is smaller than the ideal value ZC, a,. Our study reveals ...
