Profilometer Talysurf

Figure 17.4 shows the surface map of a Bionext dry membrane recorded in a Taylor Hobson Form Talysurf Series 2 profilometer.

Wear profiles anal)rsis and measurements were conducted using a Talysurf profilometer taking five measurements of the cross section and along the wear scar. 

Post-test disc wear tracks were measured with a 2-D Talysurf profilometer. For each wear track, four measurements were carried out and the average of the four measurements was used to calculate the disc volume loss, see equation (1). Pin wear scars were measured under optical microscopy. The average of two diameters (the largest and the smallest diameter across the wear scar) was used to calculate the volume loss of the pin [23], see equation (2) while the height of the worn pin can be... 

The roughness of the newly cut workpiece surfaces was measured using a Form Talysurf 50 profilometer (Rank Taylor Hobson). Arithmetic average surface roughness (Rj) values were recorded at five different locations along the length of the workpiece and averaged to obtain a mean value for the Ra- This mean Ra value is reported.
