E/M Coating Services offer a wide range of wear resistant coatings that are designed to protect surfaces, improve performance and extend the life of critical components.
Wearing of a critical component usually occurs when there is a removal of material from a solid surface as the result of mechanical action exerted by some other solid, possibly in the form of particles, or as a result of the action of strong gas or liquid currents upon a surface, especially at high temperatures. Any sliding contact between solids leads to a measurable, if small, material loss. Such losses are particularly serious in modern precision mechanisms, for if they persist they lead rapidly to mechanical failure.
Many of our solid film lubricant products provide wear resistance in applications where galling, fretting and seizing occur. These wear resistant materials enhance the base metal substrate by creating a lubricating surface, which eliminates many of the problems associated with traditional wear. Over the years, many of our dry film lubricants have solved very specific performance problems dealing with sliding and/or galling wear applications.
There are various ways of quantifying tribological effects in the laboratory and at E/M Coatings we use the Falex Friction and wear test machine, which allows us to measure wear life, maximum loading and coefficient of friction to ASTM D2625.
However, we would recommend that any wear resistant coating choice should be evaluated on actual trial components, as ‘real life’ wear characteristics may differ from those seen in laboratory tests, contact us to discuss your requirements in more detail.

Often the failure of subsea bolts has been a major cause of gas or oil leakage in offshore installations, so along with the access difficulties for
