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.

Ultra low friction coating to solve material challenges. The advantages of apticote 480a are not only limited to low friction and non stick. Most coating ideal for the forming industry and dry machining. 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.

The magnacoat range of coatings are probably the best corrosion resistant coatings available. 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. The coatings provide excellent barrier protection to resist aggressive chemicals and other sources of corrosion. 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.

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.
