In the conditions of fretting corrosion, the vibration burnishing method that creates a regular microgroove pattern is able to compete with the traditional methods of surface covering (galvanic, sprayed and other).
An internal investigation conducted by Ikaria in April 2010 showed that fretting corrosion, or micro-movement at the electrical contact interface of non-noble metals, such as tin, was the cause for erratic nitric oxide (NO) monitoring readings which were reported when the INOMAX DS was used for NO delivery to patients.
The unit combines a rubber spring and integrated hydraulic damper to isolate wheel vibrations, and a tapered bearing whose use of polymers reduces wear, grease contamination, and fretting corrosion.
Oil is directed top down across the male spline through the female spline providing constant wetting of the splines; which minimizes fretting corrosion," Finocchio said.
Capable of being close coupled with standard NEMA and IEC frame motors, the SWIFT motor connection system eliminates fretting corrosion.
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.
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.
Also, a lateral attach bracket that attached to the trunnion by two bolts and riveted to the aft side of the wing spar indicated fretting corrosion at the lowermost area, another indication of movement due to of failed fasteners.
