How MODENGY coatings can extend service lifetime of the wind turbines components

One of the major directions of the Russian wind-power engineering is production of the reliable and low-consumption generators that require minimal maintenance or repairs. All turbines with no exception operate under extreme conditions causing premature wear of the plant components.

The turbine shaft bearings, planet gears, and rotating shafts (metal-to-metal friction pairs) undergo to high loads, and lubrication shortage. The elements made of hardened steel or metal alloys can get destroyed as a result of scuffing, surface fatigue, corrosion, and general wear.  

A productive and durable wind-power station is the main target of the wind-power engineering. However, in the course of time, the operators inevitably face the significant costs for maintenance, repairs, parts replacement. The budgets have to take into account expenses for modernization, logistics (including the cranes for on-site repairs), and funds to pay to the qualified personnel who can hold the required repair works.  

As wind-power engineering develops on, the power plants are getting higher and mightier, accordingly, and their units are supposed to be bigger and more reliable. Sometimes, a project on designing a wind power station can work out extremely expensive at operating, that’s why the wind power station operators do their best to extend service lifetime of the turbine components.

One of the ways to extend service life of the parts is to choose quality conventional lubricating agents for maintaining them. The other variant is to use special coatings developed to reduce friction and wear of the highly loaded units. The research results and tests demonstrate that use of such materials significantly improves reliability and extends service lifetime of the wind turbine mechanisms. These are anti-friction solid-film coatings (AFSFCs) from the Russian Modengy company.

MODENGY 1003 anti-friction solid-film coating forms a protective barrier between the surfaces in a metal-to-metal pair that reduces friction of the mating elements, protects the parts against wear, corrosion, and fretting-corrosion. This in its turn minimizes possible structural damage. The units get more reliable, and fail much less often, and due to this time spent for maintenance and equipment downtime cuts down.

MODENGY coatings are used on the parts of a wide range of dimensions and configurations. This is especially important in the wind-power engineering since the wind plants get bigger and higher in order to use advantages of the higher speed wind. For example, the ring gears in the large reduction gears can be up to three meters in diameter.

MODENGY 1003 is applied by the standard painting methods, and polymerizes at heating in kiln or at room temperature. After curing, a resistant dry layer forms on the part surface that has high load-carrying capacity, and operability under extreme operational conditions. Due to this, service lifetime of the wind energy stations extends significantly.

The Modengy company provides services on applying the coatings at its own Engineering Center located in Bryansk town.
