| Abstract: |
| The work aims to improve the microhardness and wear resistance of H13 steel surface by multiarc ion plating coating technology. The CrAlN coatings were separately deposited on the surfaces of untreated H13 steel, quenched H13 steel and nitrided H13 steel. The microhardness and friction and wear properties of CrAlN coatings on these three substrates were studied. The coating surface was relatively flat and white small particles appeared. The microhardness of the CrAlN coating on H13 steel after quenching and nitriding treatment reached over 3300HV, which was more than 14 times that of the substrate. Compared with the friction coefficient of the substrate, the friction coefficient of H13 steel after quenching and nitriding treatment was lower than that of the substrate, while the friction coefficient after coating was higher than that of the substrate. The wear mechanism of CrAlN coating on nitrided H13 steel was an interaction of adhesive wear and abrasive wear, while the wear mechanism of CrAlN coating on quenched H13 steel was mainly attributed to adhesive wear. The wear resistance of CrAlN coating on quenched and nitridedH13 steel increases greatly. |
