Korolon™ 800

Korolon™ 800 developed by MiTi® has elasticity and very low friction up to 800°F. MiTi® have developed proprietary adhesion technologies to provide dramatically improved abrasion resistance to metals and also high temperature capability. Process parameters are controlled to optimize the properties critical for high temperature applications. The crystallographic type and size are also varied for specific physical specifications.

TRIBOLOGICAL PROPERTIES
Extensive friction and wear testing has shown that Korolon™ 800 has excellent wear and friction performance under high temperature conditions. High temperature, high speed testing was conducted on a sophisticated tribometer using a coated Inconel X750 pad on an Electrolyzed 718 disc set-up (contact pressure was 21KPa). The Korolon™ 800 gives a slightly higher service temperature than the Korolon™ 700 but both show excellent friction performance as well as protecting the underlying substrate surface from wear.

SURFACE OBSERVATIONS
Structure - A dense, non columnar, quasi-amorphous structure with surface finish in the range of 0.3-0.4µm. Excellent surface adhesion and good release properties. Process parameters are controlled to optimize the properties of the coating for specific applications. These coatings are designed using sub-micron sized particles with specific binders, since this can significantly influence the tribological performance of the coating.
