Advantage of tipped pcd inserts over full faced pcd inserts is the lower cost, tipped insert is one use only economical type, it requires a carrier like tungsten carbide base as substrate for the insert, and substrate have a pocket that will accommodate and support the tip, the working tips are brazed to tungsten carbide base, 1~4 tips depends on different insert shapes, this braze joint of tipped pcd inserts represents the weak link not so good as full face pcd inserts, the maximum cutting depth is not more than 80% of the tip length. These are better and cheaper than that of the full top surface pcd inserts and also offer a better surface finishing. These are highly beneficial and have different characteristics and advantages. These inserts are manufactured especially for different types of technologies and other advanced material processes.

The tipped inserts are mainly used for the turning and milling non-ferrous hard metals and also the most conventional option for machining. As pcd is a polycrystalline form of diamond, so the cutting temperature is limited and could not exceed 700в„ѓ, also the work material has no affinity with carbon, advantages of lower cost and higher productivity make pcd inserts with tipped pcd cutting edges are widely used for machining non ferrous metals of tungsten carbide, aluminum, copper, zinc and non metals material of plastic, rubber, wood, ceramics. Compared with grinding, both technical and economic benefits can be achieved by pcd inserts turning and milling, performance of tipped pcd inserts are significantly better than that attainable with conventional tool materials. Tipped pcd inserts could be used for fine to super fine precision machining, continous to interrupted machining, to obtain a good surface finish. The achieved results indicate that the AgNPs/CQDs nanohybrid with high reproducibility, repeatability, and stability has a favorable capability in electrochemical sensors improvement.Home > Tipped PCD insert > PCD insert shape C Finally, the prepared nanohybrid modified electrode was effectively applied to the H 2O 2 detection in the disinfected fetal bovine serum samples, and the recovery was obtained about 98%. In the optimum condition, the linear range of H 2O 2 determination was achieved from 0.2 to 27.0В ОјM with high sensitivity (1.5В ОјA/ВµM) and the limit of detection was obtained about 80В nM ( S/ N=3). The electrochemical investigations show that the AgNPs/CQDs nanohybrid possesses an excellent performance toward the H 2O 2 reduction.

Then, the AgNPs/CQDs nanohybrid was casted on the glassy carbon electrode in order to prepare an amperometric hydrogen peroxide (H 2O 2) sensor. The as-synthesized CQDs and AgNPs decorated CQDs nanohybrid (AgNPs/CQDs) were characterized by UVвЂ“vis and photoluminescence spectroscopy, Fourier transform-infrared spectroscopy, transmission electron microscopy, atomic force microcopy, X-ray diffraction, and field emission scanning electron microscopy. The silver nanoparticles (AgNPs) were embedded on the surface of CQDs by ultra-violate (UV) irradiation to the CQDs and silver nitrate mixture solution. A simple, low-cost, and green process was used for the synthesis of carbon quantum dots (CQDs) through the hydrothermal treatment of salep as a novel bio-polymeric carbon source in presence of only pure water.
