Alloying as a way of improving material properties has really gained a lot of global attention over the past few years. Alloying majorly improves physicochemical, electrochemical, thermal, and mechanical and corrosion resistance of a parent material. In this work, electrodeposition using a sulphamate electrolytic cell under varied concentrations of the secondary phase of cobalt. Characterization of the alloy was achieved using scanning electron microscopy (SEM), optical microscopy (OM), and X-ray diffraction (XRD) techniques. Corrosion resistance was investigated using potentiometric and impedance tests, reported, and well explained.

The Zr -doped TiN coating, a nanometer (Ti, Zr)N thin film, has been deposited by reactive magnetron sputtering on slides and Al substrates. The crystalline phase and energy band structure have been analyzed by XRD and STS. The results of XRD show that the (Ti, Zr)N film is poly crystalline and consisted of mixed crystal of TiN and ZrN phase. The STS spectra show that Zr -doping didn't change the position and band-gap of energy level, only two new energy levels appeared, Eg = 0.33eV and Eg = 0.42eV. According to the results of measurement, (Ti, Zr)N has higher hardness and better corrosion resistance than TiN by Zr -doping.
