Mechanism of action
Processing of units, assemblies and mechanisms using tribological technical compositions NEODRIVE can be carried out by introducing into a standard oil system, grease, or applied directly to the workpieces before assembly. Getting on the friction surface of the working mechanisms, particles of friction nanomodifiers modify the surfaces of friction pairs.
The technology of processing nodes and mechanisms with NEODRIVE compositions is one of the methods to increase the wear resistance of machine parts and equipment based on the wear-free effect in the implementation of selective transfer.
Selective transfer is a special type of friction that is caused by spontaneous formation in the contact zone of a thin, non-oxidizing metal layer with low shear resistance and inability to rivet. Such a protective layer is called servo.
The servo layer is a special structure on the friction surfaces, characteristic of the effect of wearlessness. The protective layer separates the working surfaces and protects them from wear, having high wear resistance and low coefficient of friction.
NEODRIVE tribological compositions create the conditions for transition of the tribotechnical system to a new, higher tribotechnical level, self-organizing processes allow to form a layer of such thickness that is most suitable for this assembly, materials of friction surfaces, lubrication properties and operating conditions. Under the conditions of the necessary and sufficient amount of a nanomodifier of friction in a lubricating medium, the layer thickness will self-regulate depending on the temperature and load in the contact zone. With a decrease in temperature and load, the layer stops growing; with an increase, the construction of the layer continues. Moreover, the layer is formed not on the entire friction surface, but only in places of increased loads.
The protective layer is a single crystal of a special type, which have a 50-60 times more voluminous crystal lattice than metal crystals of a worn surface. Therefore, they in the total mass rise above the surface of the contact spot, thus compensating for metal wear.
The formation of a layer on worn friction surfaces is a controlled process by the friction system itself. The properties of the protective layer and its thickness are determined solely by the current conditions of the friction zone: load, speed, temperature. This is due to the transition to optimal conditions for the friction unit.
The restoration and maintenance of compression provides favorable conditions for the combustion of fuel, which leads to passport values of fuel consumption, reduction of carbon formation and toxicity of exhaust gases, restoration of engine power and acceleration. The restoration of gas tightness of the cylinder-piston group reduces the breakthrough of gases in the crankcase, which ensures the necessary resource of lubricating oil by reducing its oxidation and the ingress of carbon particles. A thicker layer of oil shifts the friction mode closer to the hydrodynamic friction zone, which allows to reduce friction losses and increase power.
NEODRIVE compounds provide the formation of a new structure on the friction surfaces of assemblies and parts. In the engine, these are parts of the cylinder-piston group, the crank mechanism, the gas distribution mechanism, the plunger pairs of the injection pump, gears of oil pumps, pushers, guides, rolling and sliding bearings. In gearboxes and differentials - these are gears, rolling bearings, spools. In power steering - these are hydraulic pumps and actuators.
Processing of nodes and mechanisms is carried out in one stage. NEODRIVE is added to old oil. The quality of the oil does not matter.
FORMATION OF A NEW PROTECTIVE LAYER AT FRICTION NODES HAPPENS IN SEVERAL STAGES
Surface preparation - fine cleaning of the surface layer of friction pairs deformed during operation. The cleaning function is performed by a certain group of minerals, providing instant surface cleaning and, at the same time, the particles of minerals themselves are destroyed.
The formation of the protective layer is the formation on the prepared surface of the metal of new layers of the crystalline structure, which is a continuation of the metal substrate of the rubbing parts. The protective structure grows in the “layer by layer” mode. The layer first grows with thin scales, then it combines into plates and turns into a continuous surface. In this case, traces of scoring, scratches and chips are closed. The material for the construction of the protective layer is iron, which is in the lubricating oil (lubricant) in the form of wear products, as well as substances that are part of the friction nanomodifiers. The formation of the protective layer is influenced by carbon from the hydrocarbons of the lubricant.
Dynamic regulation of the protective layer - maintaining the protective layer with the parameters necessary for the friction system for the optimal state in a particular operating mode. An ultra-microporous structure of increased strength is formed with increased oil-holding ability, which provides a whole range of unique properties of the assembly, mechanism, assembly and internal combustion engine. These parameters include: layer thickness, porosity, waviness, roughness. If there is even an insignificant amount of the composition of the friction nanomodifier in the lubricant, dynamic control of the parameters of the protective layer occurs. During this period, the processes of wear of the contacting friction surfaces are practically absent, since the protective layer has an increased oil-holding ability, the friction mode is shifted to the zone of the hydrodynamic friction mode, at which the wear is minimal.
