The application of plastic materials in various areas of contemporary technology can lead to improvements in the function, quality and performance of engineering components. When determining the field of use of these materials, it is necessary, in addition to knowing the physical and mechanical properties, information about their behavior in service under the influence of the operating and environment factors. Compared to metallic or ceramic materials, polymeric materials exhibit a wide range of scratching deformations in a narrow range of pressure, speed, temperature, lubrication etc.In this paper is proposed a penetration model of a flat surface (from polymeric material) with a rigid conical penetrator and the determination of the flat surface material response mode. The penetration method corresponds to the deformation produced by the asperities in practice.The comparison of the experimental and the theoretical results confirms the veracity of the model and corresponds with many of the experimental results obtained in the specialized works.Based on the proposed models, maps can be produced, that can illustrate the response of any polymeric surface in contact with an abrasive material.

“…As it is known from the literature [10,11,[17][18][19][20][21][22][23][24][25][26][27][28][29]] the appearance of a wear or other shape depends, in particular, on the ratio of the hardness of the surfaces in contact, the surface processing mode, the contact pressure between the conjugated surfaces, the exploitation conditions, etc. Abrasion wear is a form of wear present in most slip-resistant couplings with essentially different hardness but is also accompanied by other types of wear depending on the kinematic coupling specificity.…”

The working conditions of the composite materials used to produce machine parts lead to different forms of wear. The fact that, for example, for a a kinematic coupling with sliding motion is often used a material with higher hardness (cast iron, steel) in combination with a material with a lower hardness (a composite material) there is the possibility of wear through abrasion and local plastic deformations. The paper proposes an analytical model for the determination of wear, depending on the angle of inclination of the roughness of the hard surface. The experimental wear investigations were made on cast iron disc (300HB hardness) at room temperature using a "pin on disc" machine, at and contact pressure and sliding speed. The composite consisted from cast and heat treated AlSi12CuMgNi and AlZn6MgCu matrix reinforced with Al2O3 and Graphite combined in different proportion, in the 0-5 volume percent range. The experimental results of the wear for the different materials are analyzed and compared to the analytical ones. The comparison of the experimental and the theoretical results confirms the veracity of the model and corresponds with many of the experimental results obtained in the specialized works.
