Metal parts and components can easily become damaged due to surface friction through contact. Traditional types of lubricants offer some reduction in wear caused by friction, but this is limited.
Adding anti-wear friction modifiers to the lubricant extends the ability to protect the surface of the metals or other solid surfaces. There are different options in these modifiers that are used for various applications, including for boundary lubrication.
In general, these modifiers have a polar end that bonds with the metal surface and an oil-soluble end that extends from the surface of the metal. The oil-soluble ends create a soft cushion that prevents contact between the metal surfaces.
OFM
The OFM category of anti-wear friction modifiers includes a variety of different options that are amphiphilic surfactants used in oils, transmission fluids, and also in different types of fuels. The surface of the metal components absorbs these modifiers and forms a monolayer that protects from friction.
Polymers
These modifiers can be created to work on different types of surfaces. Customizing anti-wear friction modifiers to the specific application helps to reduce friction on surfaces.
Specific types of friction modifiers also respond to the load to create a better level of friction for optimal performance. This is essential in an automatic transmission where consistent friction allows smooth gear changes when gearing up or down.
Choosing the right option in friction modifiers that provide anti-wear benefits extends the life of parts and components. This is particularly important when high heat, pressure, and surface contact are a consideration in the application.
