DURALLOY® is an extremely hard, crack-free, precise, very thin and ultrapure type of chromium coating for optimized friction processes. Thanks to the low process temperature, there are no structural changes in the base material. This significant advantage ensures dimensional stability and rigidity.
DURALLOY® coatings protect against pressure loads, poor lubrication, fretting corrosion and vibration-induced corrosion. The coatings are able to withstand high temperatures as well as corrosion and wear. What is more, they ensure low friction and dry lubrication. DURALLOY® coatings are particularly suitable for linear guides or ball bearings. However, they are equally suitable for components exposed to aggressive gases (in mills, smelting works or defense engineering).
The micro bead structure of our DURALLOY® coating is ideal for lubricant deposits. So-called lubricant pockets create an oil reservoir for extreme conditions, such as inadequate lubrication or dry lubrication.
