The combustion of Zr and (Zr+ZrO2) powdery mixtures in air was accompanied by major ZrN stabilization. The synthesis of cheap ZrN with the high yield in air was facile and utile. The influence of Y2O3 additive on the content of ZrN the solid combustion products (SCP) was investigated. The reagen...detailed
The oxidation behavior of zirconium nitride coating in high-temperature water vapor and air environments was studied. The parabolic rate constant of ZrN oxidizing in the water vapor environment at 600 °C was approximately 100 times faster than that in air, due to the larger pores and greater nu...detailed
The interest about zirconium oxynitrides is growing with the attention for zirconium nitrides phase at high zirconium content. In recent years a great progress has been made to realize both the higher nitride phase (Zr3N4) and the higher oxynitride phase (Zr2ON2) in more ordered crystal structur...detailed
Total knee arthroplasty is a well established treatment for degenerative joint disease, which is also performed as a treatment in younger and middle-aged patients who have a significant physical activity and high life expectancy. However, complications may occur due to biological responses to we...detailed
Zirconium (Zr) and its alloys are considered as promising materials for implant applications due to their excellent biocompatibility. However, the poor tribological properties of Zr are limiting its widespread applications. Therefore, in this investigation thermal nitriding of laser processed Zr...detailed
This paper reports the experimental results on synthesis of zirconium nitride from zircon sand through transferred arc plasma processing via carbothermal reduction and nitridation reaction. A mixture of zircon sand and carbon was processed in a transferred arc set-up in a stream of nitrogen gas....detailed
