This paper investigates the electrical properties of the coating based on Ti–C–B system. The coating was obtained by vacuum-arc method by spraying of multi compound cathode prepared by reactive hot pressing of Ti, carbon black and amorphous B powder mixture. The electrical conductivity of the coating was measured in temperature range of 10–320 K which was about σ = 4.8 · 103 Ω−1 cm−1 in the entire temperature range. The carrier concentration measured was about n = 1 · 1022 cm−3. The charge carriers’ mobility varies between 10 and −7 and changes sign at temperature about T = 225 K.
