The paper presents the results of experimental studies of crack resistance at the fusion boundary of the base material and the built-up layer in cylindrical specimens made of CuAl9Mn2 alloy using additive technology of powder laser surfacing. The aim of the study is to analyze possible changes in the mechanical properties of the base material at the fusion boundary under the action of high temperatures. On the basis of the experimental data it is obtained that the thermal action during laser powder surfacing has not a great impact on the crack resistance of both the base material and the built-up metal.
