Extreme durability composite diamond film
A novel composite diamond film comprising of a relatively thick layer of uncd (ultrananocrystalline diamond) with a young's modulus of less than 900 gpa and an underlying relatively thin mcd (microcrystalline diamond) layer with a young's modulus of greater than 900 gpa, has been shown to exhibit superior delamination resistance under extreme shear stress. It is hypothesized that this improvement is due to a combination of stress relief by the composite film with a slightly “softer” uncd layer, a disruption of the fracture mechanism through the composite layer(s), and the near ideal chemical and thermal expansion coefficient match between the two diamond layers.
