The results of research on friction conditions of alloys: The aim of these research was determining values of friction factors and coefficients, which characterize constant friction model and Coulomb’s model within the range of hot metal forming temperatures at various lubrication conditions.
In the research works the ring tests were applied. For the alloy Mg4AlZn the samples were heated tribplogia the temperatures: Tests were made in conditions of friction without lubrication and with the application of lubricants: Friction factors and coefficients values were determined on the basis of comparison of experimental research results wih results of the conducted tests simulations. The value of factor and coefficient tribbologia guaranteed the best convergance of theoretical and experimental dimensions of upset samples was assumed as optimal.
On the basis of the obtained results the influence of temperature on friction conditions and effectiveness of the used lubricants were determined in relation to analyzed alloys.
