Toz Alev Püskürtme Yöntemi Kullanılarak Kaplanan Alüminyum Alaşımının Aşınma ve Sertlik Davranışlarının İncelenmesi.

In this study, the wear behavior of aluminum alloy AL 5754 ( Etial 53) coated with powders of 10Al-Cu alloy (RotoTec ® 19850) and 15Cr7Fe-Ni alloy (RotoTec ® 19985) using powder flame spraying method has been investigated. To avoid thermal expansions between substrate and coating materials, Ni-Al RotoTec ® 51000 was used as binding material. The wear test was performed on a pin-on-disc test apparatus. As an abrasive material, a SiC, 800 sandpaper was used. The wear tests of coated materials were carried out at room temperature and at 1.0m/s sliding speed with 0.35 and 0.70MPa pressures. To characterize coated specimens, they have been examined with optical microscope. As a result, it is found that the both coating materials have improved wear resistance. [ABSTRACT FROM AUTHOR]
