In this study, the corrosion resistance of titanium nitride (TiN), nitrogen carbide (TiCN) and titanium-diamond-like carbon (Ti-DLC) films deposited on 316L stainless steel (SS) were compared via differences in surface section-cross morphologies, open circuit potential tests, electrochemical impedance spectroscopy potentiometric tests. The TiCN Ti-DLC significantly improved because (TiC) crystals that obstruct corrosive species penetrating as-deposited film electrolyte atmosphere. TiN...
The TiN-ZrO2-B4C reinforced Cu-metal matrix composites were prepared using powder metallurgy, and the microstructure, properties, friction mechanisms investigated when paired with self-made C/C-SiC materials. Appropriate TiN/ZrO2 ratio (3/5) can enhance performance of Cu, due to formation TiB2 through diffusion reaction between TiN B4C, while excessive may weaken it because continuity Cu is destroyed. As content increases, materials undergo abrasion wear, adhesive oxidative abrasive...
In this study, TiN, TiCN, and Ti-diamond-like carbon (Ti-DLC) films were coated on 316 L stainless steel (AISI L) substrate surface by physical vapor deposition. The biocompatibility of the three (TiN, Ti-DLC) metals L, Ti, Cu) was compared basis differences in morphology, water contact angle measurements, CCK-8 experiment results, flow cytometry test findings. TiN TiCN is similar to that AISI which has good biocompatibility. However, Ti-DLC relatively poor, mainly due inferior...
A series of Zr/Ti ratios varying from (40/60) to (60/40) were carried out for regaining the morphotropic phase boundary (MPB) region in PZT system. In order optimize ratio required, systematic study was conducted exploring effect on composition, microstructure, and electric properties by different ratio. The XRD refinement used quantify relative content rhombohedral tetragonal phase, results show that MPB moves as well optimum two phases coexistence is re-obtained at (55/45). sample with...
The effect of microstructural evolution on mechanical behavior carbon/carbon composites after heat treatment have been investigated. Two kinds samples heat-treated at 2300 °C and 2700 were used in the current study. As temperature is °C, pyrolytic carbon acquires a higher orientation due to rearrangement atomic layers, accompanied by such as self-healing concentric ring cracks, narrowing fiber/matrix interface bridging between adjacent fibers. This results significant reduction properties...
