Popis: | A bronze-5% ferrochromium composite material possesses the optimum tribotechnical characteristics in friction with lubrication, P=7 MPa, and v=1 m/sec. With an increase in ferrochromium content in the 0–10% range the hard inclusions hinder plastic deformation of the matrix. As the result there is a reduction in the capacity of the surface layers to distribute deformation under the action of contact loads in friction, that is, to run in to the abradent. Simultaneously, with an increase in ferrochromium content in the composite, the load in rubbing is absorbed to an increasing degree by the hard inclusions. With a ferrochromium content up to 5% the optimum combination of plasticity of the material and the capacity of the hard inclusions to absorb the load in rubbing is provided. |
