Friction modifier additives, also known as boundary lubrication additives are polar molecules. Manufacturers add them to lubricants to reduce the number of light surface contacts potentially occurring during metalworking operations. These oil soluble chemicals are also added to a variety of fluids intended for transmissions and internal combustion engines in the automotive and transport industries.
Types of Friction Modifier Additives
A friction modifier additive is applied with one major purpose in mind – to facilitate smooth interaction between metal surfaces, therefore, preventing wear and tear. The major types include:
- Organic friction modifiers
- Functionalized polymers
- soluble organo-molybdenum additives
- dispersed nanoparticles
These operate differently to achieve similar goals.
When the contact between metal components intensifies, industries turn to extreme pressure (EP) chemicals. This type of friction modifier additive forms a layer of organo-metallic salts. These serve as sacrificial films, therefore protecting the base metal from any destructive surface damage.
EP additives are divided into two major types:
- Temperature-dependent: Examples include boron, chlorine, phosphorus and sulfur
- Non-temperature dependent
Both types provide the added layer of protection to reduce or prevent any potential damage from the contact between various metal parts during the manufacturing process or other operations.
Friction Modifier Additives
When it comes to preventing serious damage resulting from the contact between metal components during an industrial application or in the operation of a vehicle, one adopted method has proven successful. This is the introduction of friction modifier additives to the lubricant. In the cases of more intense pressure, EP additives provide the necessary protection.
