In this study a method of predicting the adhesion strength of Chromium aluminum nitride (CrAlN) coating on Al?Si alloy(LM28) using fuzzy logic technique was introduced. LM28 was coated with CrAlN under dissimilar coating conditions. TheCrAlN coated substrates adhesion strength was determined by micro-scratch apparatus. The microstructure, topographicalanalysis and composition of selected coated substrates were characterized using scanning electron microscopy coupled withEnergy-dispersive X-ray spectroscopy. A fuzzy logic model was applied to predict the adhesion strength of CrAlN coating onLM28. RF power, DC power, nitrogen flow rate, and temperature based on the trained data achieved from the micro scratchtest were used as controllable process parameters. Then, three new experimental confirmation runs were conducted to verifythe results predicted via the Fuzzy model. The predicted adhesion strength was equated with measured data. The maximumprediction error was 5.2%, while the average prediction error was 3.5%. Finally, prediction resulted in the improvement ofsurface hardness value from 0.9 GPa to 4.5 GPa, signifying an enhancement by 5 times.
