On the basis of experimental data, the pressure at the actual contact spot of a metal plate sliding over soil is determined. The pressure may significantly exceed the hardness of the plate. Equations are derived for calculating the effective frictional coefficient at abrasive contact.

1. Changing the coefficient of mutual contact of a friction pair composed of a sintered iron-graphite material and a steel affects the operating conditions of the pair. Increasing the value of Km to unity is accompanied by a deterioration in the service performance of sintered iron-graphite materials under endfriction conditions at speeds of 11–50 m/

Phenomenological descriptions of transport processes in isotropic, non-reacting systems are discussed in terms of resistance coefficients, friction coefficients, generalised diffusivities and conductance coefficients. These quantities are defined rigorously, and it is shown that, for a non-viscous system containing n species, there is a set of (n– 1)2 ...

1. Aluminum in amounts of 0.4–0.8% decreases the hardness, friction coefficient, and wear of austenitic manganese cast iron containing high concentrations of carbon in contact with lubricated and unlubricated quenched steel. 2. The austenitic cast iron in contact with quenched steel has a considerably higher wear resistance and lower ...
