MODENGY 1025 anti-friction coating: extending service lifetime of heavily loaded friction units

Introduction

At designing the anti-friction solid-film coatings, the Modengy company constantly strives for improving performances of its materials.

In year 2025, MODENGY 1025 coating with improved anti-friction properties and extended service life was designed and released.

It is intended to solve the most complicated tribological tasks in equipment of various industries.

Composition and properties of the product

MODENGY 1025 is an anti-friction solid-film coating based on molybdenum disulfide and polytetrafluorethylene (see Fig.1).

Such combination of the components makes the coating multipurpose: it effectively operates both in metal-to-metal friction pairs at heavy loads, and in metal-to-polymer pairs. In both cases, this product is applied onto metal surface.

High content of solid lubricating substances and their special form as well as specifically selected binder provide improved anti-friction features and wear resistance of the coating making it the perfect choice for complicate operational conditions.

Uniqueness of MODENGY 1025 is in stable friction coefficient that does not grow as the layer wears off while for some other coatings this parameter increases in process of wearing off.

This product has been created for application in high-loaded low-speed friction units such as earth-moving machinery, for example.

Due to the composition features, this coating is resistant to sedimentation, has anti-settling properties. This means that this material is easy to stir after long-term storage in the container.

The basic properties of MODENGY 1025 coating are:

• Low friction coefficient within a wide range of contact pressures due to optimally selected composition of solid lubricating materials
• High load-carrying capacity (2,500 MPa) - Effective protection against fretting corrosion
• High anti-corrosive properties (> 477 hours according to the results of accelerated tests in the salt mist acc. to ISO 9227)
• Long service term (depending on unit structure, it can serve as lifetime lubrication)

This coating is used in standard sliding friction units including bearings, guideways, lead screws (see Fig.2), splined joints, gearings.

It gains positive reviews from the Russian manufacturers who make strategically important decisions on implementing MODENGY 1025 into their products production cycle including concerning replacing conventional lubricating materials used before by this coating.

This transition enables to significantly extend service lifetime of high-loaded important equipment, and to optimize production processes as this coating requires no frequent renewal, and it often performs function of lifetime lubrication throughout the entire service term of the units.

MODENGY 1025 is characterized by a relatively low cure temperature (+150 °С) in comparison with many other coatings, due to what it can be applied onto the materials (some alloy, for instance) that are less resistant to high temperature exposure.

How to apply: 

• Clearing and degreasing the parts to be treated. In order to create a dry clean surface having the roughness parameters that are required to provide the best coating adhesion, and to achieve maximal performances, it is recommended to carry out micro-sandblast treatment with fine particles  
• Finishing treatment of the surfaces with MODENGY Special Cleaner-Activator (see Fig.3)
• Applying the coating by the method of spraying out of a pneumatic spray-type handgun MODENGY M1-250 in 2 to 3 layers with in between drying during 10 minutes for each layer 
• Letting the coating polymerize on the surface during 40 minutes since the moment of heating the part up to +150 °С 5. Quality control of the gained layer: checking layer thickness (20 micrometers is recommended), polymerization completeness by using MODENGY 1013 solvent, and adhesion.
