The tables below give the wear coefficients for the mobiles and the obstacles for several pairs of materials (mat1 is the material of the mobile element and mat2 that of the obstacle). The empty boxes correspond to zero coefficients. A certain number of situations are currently planned without all the coefficients being available because this database can be completed with the results of the tests carried out at Department MTC.
