METHOD FOR TREATING INSERTS OF SLIDING BEARING ASSEMBLIES Russian patent published in 2007 - IPC B23H9/00 C23C26/00 C23C28/00 

FIELD: electrophysical and electrochemical treatment processes such as electric-erosion alloying, possibly treatment of surfaces of inserts of sliding bearing assemblies.

SUBSTANCE: method comprises steps of applying onto working surface of inserts by electric-erosion alloying with use of tool-electrodes layers of silver, copper and tin-base babbitt. Electrochemical coating of silver and copper is applied at pulse energy 0.01 - 0.05 J and coating of tin-base babbitt is applied at pulse energy 0.01 - 0.06 J. Coating layers are applied in different directions: crosswise, lengthwise and by inclination angle relative to surface at least of one block of inserts. Inserts having micro-relief on their working surfaces feature enhanced carrying capacity.

EFFECT: improved operational reliability, carrying capacity of inserts.
