The effects of abrasive particle size on the sliding friction coefficient of steel using a spiral pin-on-disk apparatus

Characteristics of Abrasive Particles and Their Implications on Wear

“…In these cases, a possible explanation for the failure of a particle to penetrate another surface is that the geometry of the particle that is not sufficiently hard to produce a scratch on the other material must have undergone a change after its breakage. The particles indeed break, as has been shown in an earlier study (Pintaude et al, 2003). Thus, instead of having more points to cut with, the broken particle ends up becoming blunter, so that it cannot cut.…”

“…The wear and friction coefficients were presented elsewhere in Pintaude et al (2003) and Pintaude et al (2009), in tests performed under sliding abrasion using pin-on-disk apparatus. The tested materials were obtained from three groups:…”

“…To find μ P , the adhesive component of the friction coefficient is assumed as 0.2, so that this value is reduced from the whole friction coefficient values provided by Pintaude et al (2003Pintaude et al ( , 2009. After the wear tests, the surface roughness of worn pins was determined, using 1.75 mm as sampling length, performed in PERTHOMETER v 6.2 equipment.…”

Plastic deformation analysis of low-carbon steel due to metal hole punching using coated and uncoated tools

“…Other values obtained in abrasive system tests can also be considered. For instance, Pintaude et al (2003) found a value of 3,700 MPa for AISI 1006 steel after pin-on-disk test with glass as abrasive material under 2.83 MPa of nominal stress.…”

Revisiting gouging abrasion test for jaw crushers

“…In these experiments, the work hardening of worn surfaces was evaluated for different amounts of crushed material, to establish a minimum of cycles to measure wear in the steady-state regime. The procedures to determine hardness were described by Pintaude et al (2003). In the second set, two materials were used for this, a high silicon (2Cr-1.5Si-0.5Mo) and a manganese cast steel, evaluating the effect of the closed side set (CSS) -the minimum opening between the jaws during the crushing cycle (minimum discharge aperture).…”
