This paper's attempt is made to analyse the current status of the research with focus on the techniques used to modify the surface of titanium alloys by laser nitriding, the most often used method to improve the properties, which is caused by that nitrogen can be easily introduced into the molten material. Laser nitriding technique, microstructure and phase composition of the surface layers, surface condition, physical and mechanical properties of the titanium alloy nitrided layers were presented.

W pracy dokonano analizy stanu badań modyfikacji warstwy wierzchniej stopów tytanu. Zwrócono szczególną uwagę na technikę laserową najczęściej stosowaną do wprowadzenia azotu w warstwę wierzchnią elementów maszyn wykonanych z tych stopów. Omówiono metodę azotowania laserowego, mikrostrukturę i skład fazowy warstwy wierzchniej, stan powierzchni oraz fizyczne i mechaniczne właściwości warstw azotkowanych na stopach tytanu.
