Influence of surface roughness on normal-sliding lubrication

Influence of roughness parameters on coefficient of friction under lubricated conditions

“…Considerable amount of work also has been done to study the influence of various roughness parameters on coefficient of friction (Lundberg 1995;Myers 1962;Hirst & Hollander 1974;Bello & Walton 1987;Wieleba 2002;Singh et al 2005). Lundberg (1995) studied the influence of surface roughness on normal sliding lubrication and reported that the R max and R t were the most significant surface roughness parameters with regard to influence on lubrication. Myers (1962) conducted experiments using an inclined plane sliding tester to study the coefficient of friction between a test slider and sample disks.…”

“…It is one of the most important factors that influence coefficient of friction during sliding. Attempts have been made earlier to study the effect of surface textures on coefficient of friction during sliding (Menezes et al 2006a-e;Lakshmipathy & Sagar 1992;Määttä et al 2001;Hu & Dean 2000;Staph et al 1973;Koura 1980;Malayappan & Narayanasamy 2004;Gadelmawla et al 2002;Lundberg 1995). Staph et al 1973 studied the effect of surface texture and surface roughness on scuffing using 'caterpillar disc tester'.…”

Prediction of surface roughness profiles for milled surfaces using an artificial neural network and fractal geometry approach

“…Lee and Ren (1996) explained that surface roughness plays an important role in affecting friction, wear, and lubrication of contacting bodies. Lundberg (1995) has investigated the effect of surface roughness on the lubricant film characteristics under conditions of combined normal and sliding motion. Xiao Li et al (2003) showed that surface roughness is one of the parameters that greatly influence the friction under Mahrenholtz et al (2005) stated that surface roughness of the contacting surfaces influences the frictional properties of those surfaces during the forming processes.…”

Modeling the interaction between contact mechanisms in normal and tangential directions

“…factors [1] such as the sliding speed [2][3][4], surface roughness [5][6][7][8][9][10][11][12], temperature [1,14], normal force [12,[15][16][17][18][19][20] and the dynamic interaction of the contacting bodies [21][22][23][24][25][26][27]. Precise modeling is possible when the above mentioned factors are considered.…”

“…They observed that under different conditions, an increase in the composite surface roughness increases the friction coefficient at scuffing. The effects of surface roughness on lubricant film characteristics under conditions of combined normal and sliding motion have been studied in [6]. Mattaa et al [7] used a new slider-on-strip tribometer to study the tribological behavior of traditional and new tool materials.…”
