Abstract: High-temperature alloys have excellent high-temperature thermal strength and are suitable for applications such as aerospace industries, which suffer high loads and temperatures. High-temperature-alloy based components require a wide temperature range protection by self-lubricating materials. Traditional self-lubricating coating such as MoN suffers poor oxidation resistance and low service temperatures. The introduction of the CrN interlayer suppresses the fast oxidation of the Mo components thus improving the resistance of the MoN to oxidation and high-temperature wear. Therefore, this work designed and prepared MoN/CrN multilayer coatings on the surface of the high-temperature alloy substrates. The wear resistance and high-temperature oxidation resistance of the MoN coatings were improved by introducing the CrN interlayers. This work investigated the wear and oxidation resistance of the MoN and the MoN/CrN coatings at elevated temperatures. The results show that the MoN/CrN multilayer coatings have excellent wear resistance and high-temperature oxidation resistance. The friction coefficient and wear rate at 600℃ are 0.466 and 1.59×10⁻⁶ m³/(N·m), respectively.
