The wear mechanism of steel balls is studied by scanning electron microscope (SEM). The ZDDP is added in 1Wt.%, 2Wt.% and 3Wt.% concentration, and its presence on surfaces is indicated by Energy Dispersive X-Ray Analysis (EDX).,The maximum improvement in the wear properties for hazelnut oil is equal to 43.7% and 45.7% at 1Wt.% and 3Wt.


Studies have shown that the extreme pressure and antiwear properties of sulfur-containing compounds are closely related to the C-S bond energy in their molecular structure. The smaller the C-S bond energy, the easier it is to break and form a protective film during the friction process, resulting in a better extreme pressure and anti-wear effect.

Wear - Wikipedia

Wear is the damaging, gradual removal or deformation of material at solid surfaces.Causes of wear can be mechanical (e.g., erosion) or chemical (e.g., corrosion).The study of wear and related processes is referred to as tribology.. Wear in machine elements, together with other processes such as fatigue and creep, causes functional surfaces to degrade, eventually …
