Are you familiar with anti wear agents for lubricants?
Additives are chosen based on their capability to fill specific functions with the foundation oil in an application. By their very nature, additives provide the base oil with new qualities, suppress unwanted ones, or increase new properties. Depending on the application, additive packages can normally account for up to 30% of the volume of the formed oil.
The most frequently used packages are those for wear and friction control additives. They are primarily AW or EP additives. Mixed-film and boundary-film lubricants protect metal surfaces. These packages create sizable, chemically reactive groups. They may not be actuated if full-fluid-film lubrication is maintained.
However, as the asperities on the crowning surface start making contact, they take on a sacrifice-like quality and offer the desired shielding for the operating surfaces. It continues until they are worn out when surface deterioration starts to happen.
Although extreme-pressure compounds and anti-wear additives are sometimes lumped together with the same wear and friction control heading, there are significant discrepancies between the two functional packages.
In mixed-film and boundary-film lubrication, anti-wear additives are utilized to prevent wear and the loss of metal surfaces. Elevated loads or temperature at interaction surfaces initiate this package. To reduce wear, it functions to generate a protective film.
The process includes the additives interacting chemically with the metal edges to shield them from wear, corrosive acids, and base oil oxidation. These additives often contain phosphorus and zinc compounds, frequently in the form of ZDDP.
