AbstractNiCrAlY coatings were deposited on superalloy IC-6 by arc ion plating (AIP). Unlubricated friction and wear behaviors of NiCrAlY coated alloy IC-6 and uncoated alloy IC-6 against alloy K17 were studied. The results indicate that in wear performance at room temperature, debris came off from alloy K17 and then transferred to the surface of alloy IC-6. Both alloy IC-6 and NiCrAly coating could be oxidized after 6000 cycles. However, oxygen is not in high concentration because only a small amount of stable oxides form in such a short time even the temperature on contact surface reached 300 V. During wear process at 600 degreesC, oxides could form more rapidly on the surface of NiCrAlY coating and impeded the interaction between substrate alloys. Oxides became more viscoidal with the temperature increment on the contact surface. Therefore, the friction coefficients is higher at room temperature than at 600 degreesC.
