Influence of dry friction on the wear behavior of X52 steel—experimental study and simulation using response surfaces method

Abstract

The objective of this work is to identify the most in uential parameters on the friction coe cient and wear rate, using the response surface method. The friction tests were carried out by adopting the methodology of complete planes 2 3 at three factors ("D", "V" et "Py"), at two level for each factor. The results show a decrease in the wear rate when the three factors are at their highest level and a decrease in the friction coe cient when using minimum loads and speeds on important distances. In addition, the developed mathematical models make it possible to reveal a correlation between the test parameters and the responses studied in their studied domain. An evaluation of the volume parameters "Vmc" and "Vvv" was carried out. The morphology of the worn surface shows that the friction under a load of 1 N leads to the predominance of an abrasive wear mechanism, while a load of 10 N favors an adhesive wear mechanism, increasing the parameters "Vmc" and "Vvv" to the maximum.

Effect of Heat Treatment on Wear Behavior of Chromoly Steel

“…Analysis of the curves illustrated in Figure 4 show the variation of the friction coefficient for the tribological couple Chromoly steel (Q, Q/T)/100C6 as a function of the distance travelled. These curves clearly indicate the existence of three phases (Meddah, 2022). Friction begins with a break-in period during which the friction coefficient increases rapidly to reach a maximum value.…”

“…This behavior depends on the microstructure formed after treatment, the volumetric fraction, the morphologies, the size and the nature of the carbides formed. Moreover, the wear debris detached from the surface results in the formation of an adherent oxide film during the wear process which prevents the direct contact of the two rubbing bodies (Meddah, 2022).…”

“…This may be related to the structural state and to the adhesion of iron oxide to the contact surface. Hence, the good ductility of these iron oxides means that the nonabrasive particles promote wear by adhesion (Meddah, 2022).…”

Wear Behavior and Wear Worn Surface Analysis on Hardox Steel

“…Wear behavior of the steel was investigated with different input constrains. Abrasive and adhesive wear and its effect on material surface have been analyzed [1]. Impact of sliding velocity on wear rate was analyzed in chromium steel.…”
