Silver, silver alloys, as well as matrix based composites have been well known and applied in the electrotechnical and electronics industry for several decades. For many applications in electrotechnology, including electric contacts and brushes, unreinforced sliver alloys do not meet the requirements concerning mainly durability and wear resistance, first of all to tribological and electroerosive wear. These wear processes may be prevented by introducing to silver reinforcement particles. It can be stated, comparing recorded friction coefficient values of all investigated materials, that in the dry sliding conditions the ceramic particles introduction into matrix has its effect on the friction coefficient value lowering. If metallic particles are used as reinforcement, and in the investigated composites iron particles were used, the friction coefficient increases its value comparing to the matrix.
