Interlayers Applied to CVD Diamond Deposition on Steel Substrate: A Review

Academics and industry have sought after combining the exceptional properties of diamonds with the toughness of steel. Since the early 1990s several partial solutions have been found but chemical vapor deposition (CVD) diamond deposition on steel substrate continues to be a persistent problem. The main drawbacks are the high carbon diffusion from gas phase into substrate, the transition metals on the material surface that catalyze sp 2 bond formation, instead of sp 3 bonds, and the high thermal expansion coefficient (TEC) mismatch between diamond and steels. An intermediate layer has been found necessary to increase diamond adhesion. Literature has proposed many efficient intermediate layers as a diffusion barrier for both, carbon and iron, but most intermediate layers shown have not solved TEC mismatch. In this review, we briefly discuss the solutions that exclusively work as diffusion barrier and discuss in a broader way the ones that also solve, or may potentially solve, the TEC mismatch problem. We examine some multilayers, the iron borides, the chromium carbides, and vanadium carbides. We go through the most relevant results of the last two and a half decades, including recent advances in our group. Vanadium carbide looks promising since it has shown excellent diffusion barrier properties, its TEC is intermediary between diamond and steel and, it has been thickened to manage thermal stress relief. We also review a new deposition technique to set up intermediate layers: laser cladding. It is promising because of its versatility in mixing different materials and fusing and/or sintering them on a steel surface. We conclude by remarking on new perspectives.

“…The use of CrN as an interlayer has been extensively studied [8,[20][21][22][23][24][25][26][27]. Some authors have also used multilayer systems, such as Ni/Cu/Ti [28], Ni/diamond embedded crystallites/Cu [28] and TiC/Ti(C,N)/TiN [14] to improve diamond adhesion on steel. The Ni/Cu/Ti interlayer system [28] enabled the growth of good quality diamond films, with good adhesion being confirmed by a 200 N load indentation using a Rockwell indenter.…”

Abstract:The hardness, heat conductivity and low friction coefficient of microcrystalline diamond make it a suitable candidate for tribological applications. However, its roughness and high deposition temperature pose significant obstacles to these applications. We have successfully grown nanocrystalline diamond on steel at 400 °C by hot-filament chemical vapor deposition by employing a CrN interfacial layer. Nanocrystalline diamond combines hardness and surface smoothness required in tribological applications. Microcrystalline diamond and carbon nanotubes can also be grown by controlling the deposition parameters. The fabricated films were characterized with Raman spectroscopy, X-ray diffraction (XRD), Transmission electron microscopy (TEM), and scanning electron microscopy (SEM).

“…In a recent work [20], some of the authors demonstrated that well-adherent diamond thin films could be grown at 650°C on M2 grade high-speed steel (HSS) by using a 10μm TiC interlayer deposited by the PVD-arc technique (α TiC = 7.4 × 10 − 6 /K, Young modulus E TiC = 370 GPa). The aim of this work is to further confirm the possibility to grow adhering diamond films on HSS with arc-plated TiC interlayers obtained using a different PVD reactor and with thickness lower than those previously investigated in Ref.…”
