Abstract: The main objective of this work was to study the influence of the injection moulding process on the tribological behaviour of ABS polymers and nylon PA6.6+15% of glass fibres. The article also describes the structure of wear maps. Its topic is the preservation of the initial surface roughness at the bottom of the track in tribotesting. Testing and measurement methodologies and data processing techniques are described. ABS and PA6.6+15%GF are polymers. Their specifications state that they are both thermoplastics with very similar characteristics. Tribotesting was employed to find whether or not this is the case. The pin-on-disc method was used to obtain the data. As a summary of the experiment was created wear map that describes the behavior of the material with various input test conditions. During subsequent analysis of this map were discovered not correlating areas that were undergone to further investigation. During this investigation an unknown inclusions in the structure were revealed which are now subjected to further investigation.

Abstract: In recent years, substantial advancements have been made in the methodology of constructing material wear maps [1-3]. The maps make it possible to locate the dominating wear mechanisms in parameterized enforcement areas. The method constitutes a powerful tool for analyzing the mechanisms of material damage, the optimization of material choice and the conditions of use. Recently, the maps of corrosion and erosion wear as the function of the following parameterized enforcements have been made [3]:

Abstract: An Al-1050 alloy was processed by ECAP and HPT, respectively. Dry sliding wear tests were conducted on the as-received and SPD-processed samples under various sliding conditions. A comparison of wear rate indicated that SPD processing decreased the wear resistance. Two main wear mechanisms were observed. The initial wear stage was dominated by severe platelet wear mechanism and later wear was dominated by an oxidation wear mechanism. The results show the severe wear stage of SPD-processed Al-1050 is much longer than that of the as-received Al-1050, which is attributed to the loss of work hardening capacity after SPD processing.
