When the load is high enough to break down the oil film, the ZDDP reacts with the entire metal surface to counteract welding and to reduce wear. The ZDDP film composition and thickness are directly related to the temperature and the extent of surface rubbing. For the relatively low ...
6.12.2 Engine Oil Anti-Wear Additives The standard anti-wear additive used in all current motor oil is zinc dialkyl dithiophosphate (ZDDP). Originally discovered in the early 1940s, the use of ZDDP in automobile engine oil became widespread in the 1950s [88]. A problem with ZDDP is that ...

• Antiwear agents: Sometimes the lubricating film created by oil breaks down, so antiwear agents have to protect the metal surfaces. A zinc and phosphorus compound called ZDDP is a long-used favorite, along with other phosphorus (and sulphur) compounds. If you must know, ZDDP stands for ...
