An Investigation of the Influence of Initial Roughness on the Friction and Wear Behavior of Ground Surfaces

Abstract: Friction and wear tests were performed on AISI 1045 steel specimens with different initial roughness parameters, machined by a creep-feed dry grinding process, to study the friction and wear behavior on a pin-on-disc tester in dry sliding conditions. Average surface roughness (Ra), root mean square (Rq), skewness (Rsk) and kurtosis (Rku) were involved in order to analyse the influence of the friction and wear behavior. The observations reveal that a surface with initial roughness parameters of higher Ra, Rq an… Show more

“…In addition, on T13 curve has the longest running-in time (up to 900 revolutions) than in F18 (up to 550 revolutions). This leads to the hypothesis that R sk has an influence on the time required for the friction coefficient to reach the steady state 16 . In curves T18 and F13 the interpretation approaches the typical friction curve between metals [1][2][3]6 , with a gradual growth in friction resulting from the great interaction between the roughness and impurities present at the interface.…”

“…In some cases, small changes in the machining process can be masked by this parameter. Thus, it is recommended to use the quadratic arithmetic average R q 12,15,16 . According to García-Jurado et al 13 and Sedlaček et al 17 , R q is similar to R a , does not differentiate peaks and valleys, but amplifies (squared) occasional deeper asperities.…”

“…The low roughness value of GIVO‐0.4 % GO coated samples suggest the uniform distribution of GO in the polymer matrix formed on MS. Since the surface roughness has much influence on coating adhesion and wear resistance, the decrease in surface roughness leads to good wear resistance and adhesion property of the coating . The decreased surface roughness reduces the local corrosion and it also reduces the hydrophilic nature of the surface and hence decreases the surface contact between the aggressive solution and coated surface …”

“…It has been established that Ra and Rq is linked to the friction and wear stabilisation. 26 It was explained by Liang et al 26 that for a surface with the higher value of Ra and Rq, the friction and wear behaviour reach more quickly to their steady-state stage. Figure 11 reveals that the surface structuring has increased the roughness value, which has facilitated in early wear stabilisation.…”
