High-speed steels (HSS) have high hardness, toughness, shock resistance, and wear resistance at room and increased temperatures due to their high ratio of alloy elements. Even though the low wear resistance compared with cemented carbides is a significant disadvantage, recent advances in surface technologies have increased surface hardness and wear resistance. In the present study, the “cathodic arc vapor deposition” method from among the PVD coating methods was used for coating the sample surfaces of the glaze spray nozzles prepared using AISI M2 high-speed steel material prepared with TiN, AlCrN, AlCrTiN, and AlTiN. Scanning electron microscope (SEM) was used to identify that the coatings display a homogeneous and crack-free distribution. The micro-hardness of AISI M2 high-speed steel-coated ceramic coatings was also investigated. Accordingly, the highest hardness value was obtained for the TiN-coated sample, whereas the lowest hardness value was obtained for the AlCrTiN-coated sample. The ball-on-disc method was used to compare the wear characteristics of the samples, considering the distance from the coatings until fracture. When the wear resistance of the coated samples was examined, it was observed that the most significant increase was obtained in AlCrN coated sample compared with the original sample
