Tribological Characteristics of Nano Structured Nickel Coatings for Renivating of Extruding Shafts

The methods for wear resistance testing is described and the experimental results for the dependence of the massive wear, wear speed, intensity of wear and wear resistance on the friction road and the time of a contact interaction are obtained. A testing micromanipulator with piezo actuators for measuring the roughness of the surface layer is developed. A methodology for thermographic testing and experimental results for wear and temperature changes in the contact by the wear process of the coatings under dry friction and abrasion is obtained
