Additionally, PowerTriple Lock contacts have an anti-fretting lubricant that helps prevent fretting corrosion.
Over time, fretting corrosion results in electrical deterioration, data loss, thermal runaway and ultimately circuit failure.
Among the topics are long-lasting outdoor atmosphere corrosion tests, evaluating fretting corrosion mechanisms on the head-cone interface of hip prostheses, plasma electrolytic oxidation coatings on magnesium alloys for improved wear and corrosion resistance, the boundary element modeling of the impressed current cathodic protection of an offshore platform, and recovering current density from electric potential data.
The pressure their use causes is oftentimes the reason behind the considerable wear of crucial parts, which in many cases leads to extreme cases of wear, such as scuffing, galling, jamming and fretting corrosion damage [8].
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 main reasons for this include: the use of an incorrectly fitted shaft or housing, causing bearing damage in the form of cracked rings and fretting corrosion; and the use of defective shaft or housing seats, which are deformed under load and cause fretting corrosion.
Also, a lateral attach bracket displayed fretting corrosion.
23 December 2011 - Ikaria Inc said on Thursday that it had completed a remediation action for its INOMAX DS drug-delivery systems to address the issue of fretting corrosion.
01 -- Dow Corning Corporation, a global leader in silicone and silicon-based technology and innovation, is launching new MolykoteAG-3407 Caliper Pin Grease to help disc-brake designers reduce fretting corrosion and excessive wear on caliper guide and mounting pins.
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.
