Abstract
In this paper we present the results of a study of crack resistance of a microarc oxidation coating (MAO) after laser doping with zirconium oxide. Crack resistance was determined by indentation with imprint imaging using atomic force microscopy. Laser doping with zirconium oxide was established to lead to a significant hardening of the MAO coating. The stress intensity factor increases by a factor of 2.7 while surface damage decreases by a factor of 2 compared with the initial MAO coating.
