family feature silver-plated contacts and a polarized housing; the contacts offer significant cost-savings over gold-plated systems to help avoid the need to manually lubricate tin-plated versions to reduce fretting corrosion
, while the polarized housing prevents connector mis-mating of the header and receptacle or plug and receptacle.
The SKF Explorer VA406 spherical roller bearings with PTFE-coated bore that provides additional benefits in vibrating screen applications because the PTFE coating eliminates fretting corrosion
between the shaft and the bearings.
The Micro-MaTch connector series' contact helps prevent fretting corrosion
, the traditional failure mode in tin-plated connections.
Upon inspection Eriks engineers found that water ingress had caused internal fretting corrosion
of the main output shaft-bearing unit; while posing no threat of contamination, prolonged operation would have resulted in raised temperature and eventually seizure of the unit.
occurs between a metal component and an opposing hard surface (i.
Capable of being close coupled with standard NEMA and IEC frame motors, the SWIFT motor connection system eliminates fretting corrosion
, especially around bolt locations, plagues steel disc couplings, particularly where intermittent torque is experienced.
Norm was assigned to the Corrosion Science group of the chemistry and materials division, working on fuel development for NPD-1 and NPD-2, Upon his return to Hamilton, he continued working on the many fuel design parameters associated with prototype manufacture (welding/brazing) of early CANDU fuel (NPD and Douglas Point), In 1979, he moved to the Port Hope fuel manufacturing facility where he continued to work on development work associated with fuel/pressure tube crevice corrosion, SCC, fretting corrosion
and DHC of Zirconium, uranium dioxide, CANLUB coatings and steam generator materials.
In these cases, fretting corrosion
will be observable on the interface.
The complaint points out that "studies have shown that modular neck adapters made from titanium alloy, such as the ProFemur modular neck adapter" "are more likely to suffer fretting corrosion
and fatigue fracture than those made from cobalt-chromium.
All components in the family are fitted with a silver-plated interface that eliminates fretting corrosion
while isolating terminals on both mating sides to protect against damage or shock.
The types of corrosion that are pertinent to the currently used alloys are pitting, crevice, galvanic, intergranular, stress corrosion cracking, corrosion fatigue and fretting corrosion
(Kamachi Mudali et al, 2003).
