The ambition of this research work is to evaluate the hardness and wear behavior titanium alloy reinforced with tungsten carbide particle (WC) composite prepared by powder metallurgy route. Titanium 5 10 wt% composites was manufactured through technique. properties are measured in tests. microstructures evaluated utilized optical microscopy. fabricated exhibit improved resistance. specimens wer...

Graphene and titanium carbide MXene variants significantly reduced bacterial endotoxin induced THP-1 monocyte IL-8, IL-6 TNF-α cytokine production.

DLC-type layers offer a good potential for application in medicine, due to their excellent tribological properties, chemical resistance, and bio-inert character. The presented study has verified the possibility of alloying DLC layers with titanium, with coatings containing three levels of titanium concentration prepared. Titanium was present on the surface mainly in the form of oxides. Its incr...

INTRODUCTION Recently, we introduced a new deposition method, based on Ion Plating Plasma Assisted technology, to coat titanium implants with a thin but hard nanostructured layer composed of titanium carbide and titanium oxides, clustered around graphitic carbon. The nanostructured layer has a double effect: protects the bulk titanium against the harsh conditions of biological tissues and in th...

We tried to evaluate the carcinogenic risk of man-made mineral fiber based on the mesothelioma incidence in female F344 rats after intraperitoneal administration. Rats (female F344/ Nslc, 5-week-old, n=330) were observed for 2 years after the intraperitoneal administration of 5 to 20 mg of 9 types of the JFM (Japan Fibrous Material Research Association) standard fiber samples (glass wool, rock ...
