The novelty is designed for the parts and friction units where low friction coefficient, high wear resistance, and reliable corrosion protection are simultaneously important.
MODENGY 1044 is an anti-friction solid-film coating based on molybdenum disulfide and graphite. The combination of solid lubricating materials provides high anti-scoring properties and long service lifetime of the coating retaining its efficiency under conditions of dry friction, high loads, and increased humidity.
This coating forms a durable anti-friction film on the part surface, reduces friction, and makes running-in of conjugations easier. It prevents the parts from jamming and stick-slip motion, contributes to reducing wearing at dynamic loads. When it is used together with greases, MODENGY 1044 provides synergetic effect.
Among the key advantages of MODENGY 1044 there are the following: low friction coefficient, high load-carrying capacity, high adhesion, a wide service temperature range from −100°С to +250 °С, operability within dusty environment, and prevention of galvanic corrosion. This coating is also characterized by high anti-corrosive properties: according to the test in neutral salt mist, it retains its protective properties for 766 hours.
The self-lubricating effect of the coating provides long sliding of the parts without need in additional lubrication. A steady solid lubricating layer is formed on the contacting surfaces which is especially important for the units with obstructed lubrication feeding, at operating within a dusty environment, under high loads, and at multiple movement cycles. Such combination of features enables to use this development in the critical units operating under high loads and in aggressive media, to extend service lifetime of the parts, and to improve reliability of the equipment.
MODENGY 1044 is used in bearings, sliding guideways, in friction pairs of cylinder-to-piston type, gearings, movable spline joints, and immovable press-fit connections subjected to fretting. This coating also fits for other high-loaded metal-to-metal friction pairs where it is simultaneously required to reduce friction, prevent jamming, and provide reliable corrosion protection.
Among possible application fields are: compressor pistons, internal combustion engine pistons, hydraulic equipment sleeves, rack-and-pinion drives of the axial type valves, leadscrews, and sliding supports of the pipeline fittings.
In the oil-and-gas equipment, MODENGY 1044 can be used on the parts of the submersible plant, in the units of the packer equipment, and to protect threaded connections of the drill-pipe subs. At multiple cycles of screwing and unscrewing, the threaded surfaces are subjected to intensive wearing. The coating contributes to reducing friction, prevents jamming and thread damage as well as helps extend service lifetime of the connections.
MODENGY 1044 is the coating where conventional anti-friction properties of molybdenum disulfide are complemented by the up-to-date approach towards protecting the parts against corrosion.
