Adhesion strength prediction of craln coating on al-si alloy (LM28): Fuzzy modelling
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. The CrAlN coated substrates adhesion strength was determined by mi...
