Abstract: The article presents our experimental procedure of N-B alloying in the 45 steel surface by a CO2 laser beam.The phase structure,the distribution of the elements,the microstructure,the hardness and the resistance to abrasion of the alloy layer are examined and analyzed.The results indicate that the alloy layer will provide many strengthening effects.
