    Based on measurement results, an interpretation is presented of the tribological system boundary layer action in the form of a four-ball tester friction node. The evaluation was performed of the boundary layer action understood as transfer of energy Ep resulting from loading the tribological system in a determined time t with work lp, which may lead to breaking the boundary layer. That energy and time are the values unequivocally characterising the boundary layer action. This form of presenting the boundary layer action has also an advantage of offering a possibility of investigating it by carrying out precise measurements and expressing the results in a numerical form. Therefore, the proposed method of evaluating the boundary layer action deterioration process is the acoustic emission measurements
