The Influence of Technological Parameters of Cold Gas Dynamic Spraying on Wear Resistance of Aluminum–Carbon Nanofibers Coatings

Resumo

The microhardness, coefficient of friction, elastic modulus, elastic recovery coefficients, and plastic deformation resistance are determined for functional aluminum matrix–carbon nanofibers coatings. Wear rate tests were carried out to evaluate the wear resistance of functional coatings, as well as to predict their service life. The coatings with the best mechanical and wear resistance characteristics were distinguished as well.
