Résumé:
The work aims is to improve the structure reliability of an industrial robot by improving the tribological mechanical characteristics systems that make it up of a thermochemical borocarbonitruration treatment that leads to the hard variable thickness layer formation which increases the wear and friction resistance properties of the robot elements. This surface layer gives the borocarbonitruration its tribological function and ensures the robot has a smooth operation at a reduced cost. The results show the advantages of additive elements in the basic alloys proposed for the robot modules' wear resistance. A comparison of the results obtained with those found in the literature indicates good agreement.
