Diagnostic complex for measurement of adhesive component of friction coefficient

The description of a diagnostic complex with computer system of data receiving for measurement of an adhesive component of friction coefficient is presented. Laser pulse treatment of the contact surface in air when the size of normal contact stresses in a contact zone is ~135 МПа leads to decrease of a friction coefficient on 20 %. It is shown on the example of movable frictional contact of high+speed steel Р18 and steel 20.
