Modification of Surface Properties by Laser Cladding with Ni–Cr–B–Fe–Al Alloy
Keywords:
laser cladding, microstructure, potentiodynamic method, sliding indentation
Abstract
The paper is focused on modification of surfaces properties by laser cladding. To follow the corrosion behavior in different media of laser cladding layers made of nickel based alloy Ni - Cr - B - Fe - Al. It was studied using the potentiodynamic method. Elasto – plastic behavior of the assembly base material - deposited layer was monitored by using sliding indentation, in dry friction conditions. It was determined the bearing capacity of surfaces.
