The concern with the environment preservation has demanded increasing effort to recycle plastics. In a previous investigation we have reported the possibility to manufacture thermal sprayed coatings from recycled PET. Pin-on-disc data demonstrated that coatings had even better wear behavior than virgin PET. In the present work we have investigated the effects of PMMA content on the pin-on-disc and scratching behavior of PET-PMMA blends, in dry condition. AISI 52100 steel 6 mm balls, with and without TiN coatings were used as counterbody. The pin-on-disc wear testing were carried out under 1 and 10 N load. The scratching was performed with 1, 10, 50 and 100 N. Friction coefficient, volume and mass loss were monitored during testing. The paper also investigates on the effect of sliding speed.
