These materials were obtained using two methods, i.e. press-sinter-repress (PSR) at the refractory phase content of less than 30% by weight as well as press-sinter-infiltration (PSI) at the refractory phase content of ≥50% by weight). The results of research into both the physical and electrical properties of the outcome composites were shown. They include the analysis of the influence of the refractory phase content (W or WC) on arc erosion and contact resistance changes for the following current range: 6 kAmax in the case of composites with a low refractory phase content, 10 kAmax in the case of composites with the refractory phase content of ≥50% by weight. Keywords:composite materials, electrical contacts, arc erosion, contact resistance Affiliations:| Borkowski P. | - | Lodz University of Technology (PL) | | Pietrzak K. | - | other affiliation | | Frydman K. | - | Institute of Electronic Materials Technology (PL) | | Wójcik-Grzybek D. | - | Institute of Electronic Materials Technology (PL) | | Gładki A. | - | Institute of Electronic Materials Technology (PL) | | Sienicki A. | - | Lodz University of Technology (PL) |
