Ultra Low Friction Coatings

Refmet ceramics takes tools and components to new and extended levels of performance utilising state of the art ceramic diamond diamond like carbon and ultra low friction coatings to alleviate problems associated with adhesive wear abrasive wear fretting pick up galling and friction.

Ultra low friction coatings.

The ultra low friction described above was not observed in all tests. The ultra low friction coefficient typically in the 10 2 range of mos 2 based coatings is generally associated with the friction induced orientation of easy shear planes of the lamellar structure parallel to the sliding direction particularly in the absence of environmental reactive gases and with moderate normal loads we used and aes xps ultra high vacuum tribometer coupled to a. In a few cases 2 from 10 in dry nitrogen the friction curves were noisier with an average μ around 0 01. The coatings provide excellent barrier protection to resist aggressive chemicals and other sources of corrosion.

Most coating ideal for the forming industry and dry machining. Magnacoat low friction coatings. Ultra low friction coating to solve material challenges. Both optical observation and sem of the wear tracks showed large delaminated parts in the wear tracks showing higher friction see fig.

Where low friction coatings are needed ptfe coatings are usually used. In addition the most coating offers an ultra low coefficient of friction 0 01 0 06 much lower than that of teflon or graphite with a hardness of 1500 2000 hv and an extremely low specific wear rate 4 10 17m 3 nm.
