In this study, in solutions prepared by adding aluminum oxide, silicon oxide, wolfram-titanium carbure and titanium carbure particles, plasma electrolyte oxidation (PEO) method developed ceramic coatings on the AA7075 alloy. The phase composition of the covers has been studied by the X-ray breakdown (XRD) method. The scaned electron microscope (SEM) has studied the surface morphology of the coatings and the microbuilding of the cutting. The energy-distributed X-ray spectrometer (EDX) has made chemical analysis of the coatings. The hardness values of the cover are measured by the microVickers hardness test device. For the purpose of studying the drilling and stretching behavior of the subcutaneous alloys made of coverage, the 100Cr6 steel and aluminum oxide balls have been tested for dry sliding stretching. The volume of the material that is exhausted after the test is calculated by the surface profilometry of the exhaust profile. The results of the tests found that the surface hardness and stretching resistance of the AA7075 alloy was significantly increased with the PEO covers produced. The coatings are made up of an intense inner layer and a porous upper layer. It is determined that the coating hardness is high in the area near the bottom/cover interface, as it progresses towards the surface due to increased porosity. The covers produced in solutions containing silicon oxide particles have been found to be thicker and smoother than other covers. The lowest stretching loss is achieved in the cover produced in titanium carbure-containing solutions.
