Diamond, which is known for its hardness and wear resistance, has been used in machining for hundreds of years as a super-hard tool material. Besides, it also has the advantages of good stability and biocompatibility, which is in line with the material requirements of surgical tools used for tissue resection. Therefore, it is also very […]
The melting point of chromium is the lowest of the abundant refractory metals, but it is more than 700 degrees above that of iron. The density of chromium is slightly less than that of iron. At elevated temperatures, it acquires an adherent oxide film on the surface that tends to protect it from further oxidation […]
