A Review on Binderless Tungsten Carbide: …

2019/12/30· Three kinds of abrasive particles, including diamond, silicon carbide, and silica, were used. During the test, the normal load was 0.2 N and the total sliding distance was 50 m. The results showed that the WC–TiC–TaC had a slightly lower wear resistance than WC–Co cemented carbides, but much higher than that of common engineering ceramics Al 2 O 3 and SiC as demonstrated in Fig. 18 a.

In 2010, methane levels in the Arctic were measured at 1850 nmol/mol. This level is over twice as high as at any time in the last 400,000 years. Historic methane concentrations in the world''s atmosphere have ranged between 300 and 400 nmol/mol during glacial periods commonly known as ice ages, and between 600 and 700 nmol/mol during the warm interglacial periods.
