Ultra Low Friction Coatings

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.

Ultra low friction coatings. The magnacoat range of coatings are probably the best corrosion resistant coatings available. The coatings provide excellent barrier protection to resist aggressive chemicals and other sources of corrosion. 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. Where low friction coatings are needed ptfe coatings are usually used.

Most coating ideal for the forming industry and dry machining. Magnacoat low friction coatings. Both optical observation and sem of the wear tracks showed large delaminated parts in the wear tracks showing higher friction see fig. The ultra low friction described above was not observed in all tests.

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. The coating is also corrosion resistant with a 50µm thick layer resisting an industry standard salt spray test for well over 1000 hours a hardness of over 800hv and provides a very even coating that.
