Nanostructured DLC Coating for Protection of Dies from Wear

A traditional DLC coating has been designed to control its contents of sp2, sp3, and hydrogen atoms as well as the additive elements. In addition to this concentration control, both the density and cluster of carbon substructures were important in the advanced DLC coating design. Two types of nanostructuring were proposed to control the mechanical properties and tribological performance of DLC coatings; e.g., nanolamination and nanocolumn formation. In the former, a DLC-film consisted of multi-stacked sublayers with different densities to prolong the die life. In the latter, the nonlinear elasticity of low density carbon columns with high density carbon inter-columns, prevents the glass mold stamping die from adhesion to oxide glass.
