The current demands of steel in the industrial sectors make indispensable the
use of techniques that provide greater durability, resistance to wear, corrosion
and consequently an increase in the productivity and profitability of the
material. This can be achieved by carrying out different surface treatments. In
the present study an analysis was made about the tribological behavior of
different samples of nitrided AISI 4140 steel, with thermal treatments of
tempering at 850 ° and annealing at 200 °, 400 ° and 600 °; by Pin-Disco analysis
in a micro-tribometer brand CSM Instruments. From these tests obtained results
generated by the software Instrum X, the data is obtained in the form of a graph
of the coefficient of friction (μ) against the sliding distance, giving us an idea of
the change in the coefficient according to the treatment used.
