Diamond coatings provide additional sparkle for industry

Invisibly small diamonds might be scorned by jewellers but they have many very useful industrial applications.
Diamond coatings provide additional sparkle for industry
Ultra-dispersed diamonds (UDDs) are a new variety of tiny synthetic diamonds. Combined with other materials they can lead to improvements in that material's desirable properties. For instance, they can be combined with nickel, chrome or some polymers to make a protective coating for industrial machine parts. The presence of the UDDs not only increases the durability of the coating but also decreases its susceptibility to friction and corrosion. That durability and resistance to corrosion results in less wear to (hence, a longer working life for) the machines parts, whilst the low friction leads to a reduced need for lubrication and a lower fuel consumption by the machine. In contrast, the abrasive quality of the diamonds can also be utilized in materials to polish surfaces to an extremely high degree of smoothness. Furthermore, they can increase the service life and reproduction quality of magnetic recording media, and have certain medical applications in absorbents and anti-cancer medicines. It is not surprising that this new variety of diamonds should contain such a valuable appeal to industry as much as for their sparkling aesthetic appeal and worth.
