Contact rule for rigid-sphere models of crystal structures
Increasing thermal contact conductance in vacuum
Conventional face contact seal performance improved by incorporating spiral groove geometry, discussing liquid sodium containment
Contact transformations noting linearity, orthogonality and preservation of Hamiltonian form
K lubricated journal bearings materials friction and wear over temperature range in sliding contact in liquid K and high vacuum
Effective gap thickness and gap number relation determined from correlation of parameters of thermal contact conductance
Friction and wear of wire wound potentiometers sliding electric contacts in vacuum, evaluating lubricative powders and conductive composites
Cs contact ion microthruster system design, fabrication and flight qualification, noting control logic/power conditioning unit and electronic packaging
Radial momentum transfer rate gradient singularity near contact discontinuity in theory of interplanetary blast waves
Transient temperature distribution in two layer one dimensional slab with initially steady state heat transfer and suddenly changed thermal contact resistances
Lubricating sliding and rolling element electrical contacts in vacuum
Lubricating sliding and rolling element electrical contacts in vacuum
Study establishes the quality of chemical and galvanized protection afforded by anodized and aldozided coatings applied to test panels of various aluminum alloys. The test panels, placed in firm contact with panels of titanium alloys, were subjected to salt spray tests and visually examined for corrosion effect.
Research program studies behavior of specific high-speed, angular-contact ball bearings. Program is aimed at detailed investigation of ball-separator behavior and lubrication surface-finish effects in a specific gyro wheel.
Etchant containing chloroplatinous or chloroplatinic acid greatly reduces contact resistance between metallic surfaces. Etching results in a monolayer plating of platinum on the wafer surface, preventing oxide growth.
Dynamic liquid-solid contact angles and films on contaminated mercury
Auger spectrographic analysis on titanium-silver contact degradation in silicon solar cells
Flow rate effect on dynamic contact angle for wetting liquids in weightless environment
