hardness to yield strength ; represents material property; is real contact area; is critical contact area; is the total contact load. , , , are all dimensionless expressions.
This paper is for the friction pair between cast iron and steel, the main material parameters are showen in Table 1.
However, due to the dimensional change index and size change index may be related to materials of contact surface, processing methods, roughness and other factors, it is very difficult to determine them directly in theory, therefore, this paper will identify two parameters through experiments. 4.1 Test scheme This paper used APE500 surface morphology and UMT-3 pin-on-disk wear apparatus as experiment equipments, took the cast iron pins of UMT-3 pin-on-disk experiments as specimens, they are shown in Figure 1.

There are two possible mechanisms: the first is ceramic materials provides a cross-linked center for the PEO segment, which reduces PEO segments reforming trend, and modifies chain structure, so this effect makes the surface of ceramic particles to be Li+ channels; the second is as Lewis acid the ceramic material reacts with Lewis alkali species in electrolyte, which reduces the ion-ion coupling, and promote salt dissociation through the formation of a" ion - Ceramic Complex".

Result also shows that some raw materials are lost or damages, making it unable to be used for production such as having a mark on the product since there is no process in separating products in separate categories.

In order to understand the thermal evolution of tire tread rubber materials during rolling and skidding steps, new experimental and numerical studies were also realized on tire tread rubber.
However, numerical models based of Finite Element Method, FEM are still fundamental ways to predict the tire behaviour at higher speed, taking into account the high non-linearities related to materials especially for rubber material, and coupled phenomena (contact with friction, thermal-mechanical couplings, and internal dissipation).
The thermal evolution of tire tread rubber materials during rolling and skidding steps was also investigated; new experimental and numerical studies were realized on tire tread rubber specimens.
