Purpose: In the paper, geometric structure of the surface of A390.0 alloy, manufactured using various methods are presented, in combination with EN-GJL-350 cast alloy, which corresponds to parameters used in combustion engines. Design/methodology/approach: Alloy after a modification with CuP10 master alloy and overheating to 920°C for 30 min was analysed, and the results were compared with those of the material without overheating. Roughness studies allowed for defining the influence of technological history on the wear parameters of the alloy. Findings: Analysis of result shows that all investigated properties were improved. Significant differences between the analysed materials were proved during the analysis of friction coefficient and surface topography of wear track. Research limitations/implications: The application of modified by CuP10 aluminium alloy allows to improve parameters such as friction coefficient and wear rate. This property’s causes that this new modified material can be used in many applications where the aim is to reduce friction coefficient as well as wear rate. Practical implications: Improvement the tribological properties as well as reducing the coefficient of friction makes these materials may be used in many applications in the automotive industry such as engine cylinder, engine blocks, etc.. Originality/value: Influence of aluminium modification on chosen tribological properties and friction coefficient have been investigated.
