“…This deformation persists until a mechanical equilibrium between the areas of the surfaces is achieved and it depends on a great number of contact variables (the shape and the dimensions of the asperities, the normal load, the sliding velocity, temperature, etc.) [1][2][3][4][5][6][7][8].…”

In recent decades, the interest of researchers and engineers in obtaining competitive materials is increasing. The effects of friction on materials are quite difficult to explain due to the micro and macroscopic interactions of the surfaces of the friction couple, which slide over each other. The friction and wear behavior of sliding surfaces can be considered important design criteria. The fact that for a kinematic coupling with sliding motion, a material with a higher hardness is used in most cases in combination with a material with a lower hardness, there is the possibility of abrasion wear and local plastic deformations. The paper proposes in analytical model for calculating the coefficient of friction when a rigid conical penetrator passes over a flat surface with a lower hardness and establishing the response mode of the material of the flat surface. The penetration method corresponds to the deformation produced by asperities in practice. The proposed theoretical model will be experimentally validated on a tribological stand made in this sense. Comparing the experimental results with the theoretical ones confirms the veracity of the model and also corresponds to many of the experimental results obtained in specialized works.

“…The evolution of the friction coefficient is dependent on the specificity of the tested materials [2][3][4][5][6][7], the environmental conditions and the kinematic particularities of the test bench. Consideration of the approximately constant friction force at the same normal force, velocity, material, etc., is due to the fact that the number of interactions that occur at a given moment is higher and that the law of statistical distribution of contact processes is approximately constant.…”

The aim of the paper was to develop a device (“pin-on-disc” type) for the measurement of friction in plane friction couplings with sliding movement. On tribometric device (made in our laboratory) we can measure the friction force, friction coefficient and wear, for different loading conditions, speeds, time and material coupling. For the measurement of the frictional force as well as of the coefficients of friction, mainly the method with a resistive tensiometric transducer is used. With a DataQ DI 245 data acquisition board it is possible to record up to 2 kHz frequencies in the range of -10 ÷ +10 mV with a resolution of 13 bits. To test the functionality of the device, a preliminary test was carried out for a steel pin- on- cast iron disc, for different values of the normal pushing force. The device was calibrated and the measurement results were recorded and processed on the computer.
