wear behaviors of PEEK at different temperatures were evaluated by using a ball-on-disk oscillating reciprocating tribometer (SRV-IV, Optimol Corporation, Germany).
Increase of the resistance to fretting
as a result of implementing regular surface roughness patterns is also noted in [11; 12; 13; 14].
The results confirm that fretting
maps are effective tools to predict the fretting
fatigue properties of substrates and coatings surface modification.
As forcas envolvidas no fenomeno de fadiga por fretting
estao apresentadas na Figura 3b.
Only moving within a 10mm by 10mm envelope, the system is supported on air bearings, as mechanical bearings would suffer fretting
corrosion and due to the kinematic requirements, the carriage has been optimised in terms of mass.
Although limited research has been carried out to understand the sliding wear behavior of Ti-based alloys (9,10,12), none of the studies had ever probed into the fretting
wear of Ti-alloys in simulated body fluid environment, which has major relevance as far as the application of Ti-implant materials is concerned.
But for many, the constants tend to be a frantic pace, nonstop stress, and, you got it, fretting
As I complete my first attempt at editing Preaching Helps, I find myself joyously fretting
over my own uncertainties.
Compact cords, on the other hand, have line contacts and better fretting
Using a plate to reinstate the press bed leads to fretting
over the whole press bed making future repairs more difficult and costly.
He presents, among other things, a startlingly frank chief of staff, Andrew Card, openly fretting
that Hughes's departure will tip the balance of power to the more conservative Karl Rove, and a Karen Hughes strong, spiritual, and just wanting to go home.
While emerging economies are harder hit by these swings in energy prices (higher oil prices gobble up a proportionately larger amount of their GDP), they aren't the only ones fretting
about the latest turn of events.
