Automated scratching

Frank Ruttens, March 2011 14

Automated scratching

Based on DIN 50539

Sample holder

Various scratching geometries :

•Different hardness

•Different angle

•Different radius of curvature

Frank Ruttens, March 2011 15

100µm

Different indenter diamant indenter (r 76µm, 30°; 45°;60° of 90°) or steel ball (d 1; 2 ... 5 mm)

Different speed 10 t/m 100 mm/sec

Linear increasing or constant load Linearly increasing from 0,10 N tot 50,00 N (accuracy +/-0,05 N up to 10N and +/- 0,10 N up to 50N) or constant pressure from 1 N to 50 N

Measuring length and width Standard length 300 mm / width 35 mm Minimum length 100 mm / minimum width 15 mm Standard 10 parallel scratch spurs with a distance of 0.2 mm

Dry or wet Wet in various solvents at temperatures up to 50°C
