Abstract

Effect of load and velocity scratch-testing regimes on tribological characteristics and rheological properties of con-tact with simultaneous acoustic emission registration after steel thermal strengthening by electroarc flashing with following fast crystallization was researched. It is shown, that acustic-emission activity as indicator of relaxational ability on certain conditions of scratch-testing forms maximums. Mechanisms of acoustic emission changing and indicator of elastic aftereffect of steel in comparison with steel after thermal strengthening are discussed.
