Experimental research steel grade «steel 45» to abrasion wear, depending on the exit angle macrostructure fibers on the contact surface

This paper describes the experimental research of the influence of the angle of exit of microstructure fibers to the contact surface wear abrasion steel grade «Steel 45». The experimental dependence of abrasion wear depending on output angle of macrostructure fibers to the contact surface was obtained (considered angles: 0°, 15°, 30°, 45°, 60°, 75°, 90°). A method for obtaining samples with a specified directional fiber structure was development. Two experiments were carried out: on a friction machine of translational type and on a friction rotational type machine. The article shows the difference in wear with different types of friction: rotation motion simulates wear in bearings, translational motion simulates the movement of the piston in the cylinder or the operation of the guides.The effect of the exit angle of the macrostructure fibers on wear is determined. An analysis of the experimental data was carried out and the angles of the yield of fibers on the contact surface were found at which maximum and minimum wear was attained. © The Authors, published by EDP Sciences, 2017.
