Applicative characterization of cathodic arc-deposited Ti–B–N coatings

The MoSiSiC thin films were deposited on GCr15 steel substrate using radio frequency magnetron sputtering technique. Surface morphology, components and mechanical properties of the films were investigated by scanning electron microscopy, energy spectrometer, friction and wear tester and scratch tester, respectively. It was found that the surface morphology of the MoS2/SiC films prepared on GCr15 steel substrate was vermicular. The SiC inner layer and the MoS2 outer layer were binded tightly with a smooth interface and the thickness of the films was about 0.8 11m. The films-substrate system exhibited excellent friction and wear properties with a mean friction coefficient of about 0.11. Interlayers added into the films can improve the cohesion from 21 N to 26 N.

“…Now the focus on the binary compounds turned to ternary and quaternary compounds. In recently years, the addition of boron was found can improve exhibit excellent hardness, high melting point, good chemical and thermal stability [9], so the investigation of the ternary [10][11][12][13] and quaternary systems [14][15][16][17] which contain element B became hot study and development trend gradually, especially the study on the TiBCN film. But there are many problems exist and still cannot be solved of TiBCN film, such as film oxidation, breakage, evaporation, high cost, and so on [18].…”

Fcc-TiBCN powder synthesized by boronizing of Ti was pressured into monolithic block by hot pressing (HP) method. Then the block material was machined by wire-cut EDM. The machinability and the material removal mechanisms were discussed of Fcc-TiBCN block in wire-cut EDM. Results show that the machinability of Fcc-TiBCN is satisfying. The discharge current has little relationship on surface roughness in the range of factory-adjusted optimum settings. The discharge duration and pulse interval time play an important role on the quality of machined surface and EDM machining efficiency. In order to obtain excellent quality of the machined surface, the number of power tube turned on can not exceed 6, and the pulse interval time must be as long as possible. The mini roughness of machined surface is 0.4μm～0.6μm as the number of power tube turned on is 5, the pulse interval time and discharge duration is set in the range of 20～22μs and 65～75μm, respectively. There are three material removal mechanisms of TiBCN conductive ceramic in the EDM machining process: spalling, melting and evaporation. Spalling is the main mechanism resulted by thermal stress superposing.
