Influence of the Nanostructure of Surface Ceramic Coatings on Their Tribological Properties

This study is an attempt of applying new electrolytes to obtain a new generation of oxide coatings. An oxide coating was deposited on Al(Al 99.5) aluminum. The influence of an organic additive and anodizing parameters on the nanomorphology and nanostructure of the obtained coatings is described. The nanostructure and nanomorphology of oxide coatings are determined using a scanning electron microscope (SEM). An attempt is made to apply a new oxide coating for the sliding interaction with TGK 20/5 material. The tests were carried out under the conditions of dry friction. The friction coefficient is found for the investigated sliding couple, as well as the intensity of wear of specimens made of this material. The influence of the nanostructure of oxide coating on the tribological properties of the tested couple is also determined.
