Improve Fretting Wear Resistance with Self-Lubricating Surfaces

Register for this webinar to learn how to reduce fretting wear and fretting corrosion using self-lubricating surfaces.

Overview

Fretting wear and fretting corrosion are potentially highly deleterious forms of materials degradation that can occur unexpectedly in the operation of mechanical equipment. Fretting can be caused by high frequency, low amplitude (HFLA) oscillation or reciprocation in ways that surface damage is both unpredicted and unobserved by normal observation methods. Self-lubricating surfaces may be highly effective at reducing or eliminating this damage mechanism in situations that normal types of lubrication are ineffective.

This webinar will discuss basics of fretting and HFLA wear and wear/corrosion combination. Several types of self-lubricating surfaces will be reviewed, presenting tribological testing results demonstrating favorable results in both wear and related fretting corrosion. Polymer coatings and composite bearings were both tested in fretting wear conditions, demonstrating significant performance improvements.

Key Takeaways

  • Understand the basics of fretting, fretting corrosion and high frequency, low amplitude (HFLA) damage mechanisms
  • Understand the positive effect of self-lubricating surfaces in the reduction or elimination of fretting, fretting corrosion and HFLA wear
  • Discover passive film effects in corrosion and their impact on HFLA wear and corrosion
  • Witness the impact of factors such as counterface corrosion resistance and the effects of lubricious transfer film formation in the reduction and elimination of HFLA wear and corrosion
