“…The resistivity for the Ti-B-C coatings are in general 275 also higher (~10 3 µΩ cm) than for Ti-A-C-Ag (A = Si, Ge, Sn or Cu) coatings (~10 2 µΩ 276 cm) [22] or for other comparable nanocomposites [37,38,39,40]. However, the contact 277 resistance is comparable, and the contact resistance is just a factor ~5 larger than for Ag 278 against Ag, which is remarkable since the coatings contains ~16 at.% O.…”

“…37 Today, noble metals are the most commonly used materials in electrical contacts since 38 they have low resistivity and contact resistance, combined with chemical stability [12,13]. 39 The high prices and the low wear resistance in some environments motivate 40 investigations of new electrical contact materials with good electrical properties, but with 41 better mechanical properties than the noble metals. TiC-based nanocomposite materials, 42…”

9Ti-B-C nanocomposite coatings with a B content of 8-17 at. %, have been deposited by 10 magnetron sputtering from B 4 C, Ti, and C targets. X-ray diffraction, photoelectron 11 spectroscopy, and electron microscopy show that the coatings consist of nanocrystalline 12 (nc) TiC:B embedded in a matrix of amorphous (a) C, BC x ,TiO x and BO x . The fraction of 13 amorphous phase scales with the Ti concentration, where the matrix predominantly 14 consists of free C with some BC x in coatings with a C/Ti ratio >1, while the matrix 15 predominantly consists of BC x with some free C in coatings with a C/Ti ratio <1. Nc-16TiC:B/a-BC x /a-C coatings with low amount of free C exhibit a contact resistance 17 comparable to the contact resistance of an Ag sputtered coating at loads of ~1 N against 18 an Au probe, despite the O content of ~16 at. %.

“…This peak is between the (100) TiB 2 and (111) TiC planes. A mixture of both components and the formation of a ternary phase including titanium, carbon and boron (TiB x C y ) are at the origin of this peak, as demonstrated by XANES [23]. In the TiC/a-C:H and TiC coatings, the characteristic (100), (111) and (220) diffraction peaks from cubic TiC phase were identified together with some peaks originated by a titanium underlayer and…”

The use of carbon-based coatings (hydrogenated and non-hydrogenated DLC, doped and alloyed-DLC) is of a wide interest due to its applications in mechanical components submitted to friction and wear including sliding parts in automotive engines. A tribological comparative analysis using a reciprocating (SRV) tester in lubricated and unlubricated conditions with a 4-stroke motor oil has been carried out on six currently relevant state-of-the-art coatings (namely WC/a-C, TiBC/a-C and TiC/a-C:H nanocomposites, Ti-doped DLC, BCN film and a crystalline monolithic TiC film as reference). The quantification of the fraction of the sp 2 -bonded matrix has been done by fitting of C1s XPS peak and the mechanical properties evaluated by nanoindentation. A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT 2The comparative analysis has allowed us to identify the capabilities of each system This fundamental information would be of relevance for assisting engineers in selecting best partnership for lubrication systems.

a b s t r a c t 23 This paper investigates the electrical properties of the coating based on Ti-C-B system. The coating was 24 obtained by vacuum-arc method by spraying of multi compound cathode prepared by reactive hot 25 pressing of Ti, carbon black and amorphous B powder mixture. 26The electrical conductivity of the coating was measured in temperature range of 10-320 K which was 27 about r = 4.8 Á 10 3 X À1 cm À1 in the entire temperature range. The carrier concentration measured was 28 about n = 1 Á 10 22 cm À3 . The charge carriers' mobility varies between 10 and À7 and changes sign at 29 temperature about T = 225 K. 30
