MODENGY 1090 high-temperature coating was implemented into application at producing microturbine gas-dynamic bearings petals after its tests at the manufacturer’s had been successfully completed.
This product has the highest heat resistance among all MODENGY coatings: up to +730 °С. It has been designed jointly with the Moscow Aviation Institute, one of the leading Russian educational institutions in the field of space exploration and aviation.
Due to its high heat resistance as well as to its great anti-frictional and anti-scuffing properties, MODENGY 1090 coating is efficiently used to provide standard operation of the microturbine petal gas-dynamic bearings.
A thin lubricating layer that the coating forms on the working surfaces of the petals reduces friction, and prevents wear in the transient operating modes of the power plants when the bearing parts are rubbing intensively against the shaft while a high rotary speed is not reached, and a steady air wedge is not formed yet.
This coating is characterized by a long service lifetime, and operability under extremely high temperatures, loads, and traverse speeds, due to what it has gained application at production of the petal gas-dynamic bearings.
