Influence of carbon content substrates and different coating thickness Aluminium Chromium Nitride (AlCrN) coatings was investigated and reported in the studies. Low carbon steel (EN353) and high carbon steel (EN31) rectangular blocks were used as substrates. AlCrN coatings with two different thickness was deposited on these substrates using Balzers rapid coating system machine. The morphology, crystal structure, mechanical and tribological properties (surface hardness, wear resistance and coefficient of friction (COF)) of the coatings were examined using SEM, Optical Microscope, AFM analysis, Micro-Hardness tests, Scratch Tester TR-101 and Pin on Disc testing tribometer at atmospheric conditions. It was shown that surface morphology of D C Arc deposited AlCrN coatings is affected by the substrates properties (carbon content). The increase in the carbon contents of the substrates resulted in the increase of adhesion force between the substrates and coatings. It was also found that, AlCrN/EN31 steel with smooth roughness has the higher wear resistance than AlCrN/EN353 steel substrate.
