The formula for the wear coefficient is:
( 4 )
A bearing strength (F
The unit of the wear coefficient should be given as m
to reduce the units, because the source units should be kept recognizable.
4.3
Analysis by microscope
For an analysis by microscope, the diameter of the wear crater has to be measured.
4.4
Calculation of the wear coefficient
The depth of the wear crater is calculated from the diameter. An ideal spherical cap is
assumed.
The formula for the depth of the wear crater is:
The wear coefficient can be calculated with formula ( 1 ) and formula ( 4 ) (see chapter
4.2 Calculation of the wear coefficient).
