- the gases penetrate via diffusion into gaps, seams, contact voids, and deposit on heated solid surfaces, external or internally gas- accessible, in the equipment. Upon condensation on the surface, the condensed phases chemically react to form a new solid phase as a first
- the first coating may be an infiltrant coating to bond the superabrasive tip, the tool body, and non-brazing materials together.
- TiCI 4 + CH 4 -> TiC solid + gas phase 4HCI This solid phase adhesively bonds to the solid surfaces depending on chemical affinity.
- the quality of the solid phase depends on temperature and affinity to the solid surface(s) upon which they condense. The process of infiltration, condensation and reaction to form a new solid phase continues as long as temperature is high enough and reactants are present. Once the pores are filled, then straight-forward coating on surfaces of the superabrasive tip and the tool holding material may occur.
- Gas accessibility is determined by the gas diffusion, which depends on temperature and pressure. Lower pressure allows deeper diffusion of reactive gases into seams and gaps in the tool assembly. Gas deposition, reaction and solidification rates forming a solid must be controlled to prevent premature '"plugging" of narrow gaps and seams, thus reducing the film contact area and joint strength. This typically requires that the temperature be lowered, or gas phase partial pressure of reactants be adjusted. Finally, the quality of the film formed, its crystallinity and crystal orientation, depends on temperature and time. If the film is formed and quenched too quickly, it may be of poor quality and crack either within the film or at the film-tip or film-tool interface.
- non line-of-sight CVD coating does not require tools to be flipped over and processed multiple times to form a uniform coating.
- CVD coats all gas-accessible surfaces in one furnace cycle.
- Gas phase reactions that may also be considered CVD include any gas- solid reactions such as oxidation, hydration, or carburization.
- the solid constituents include any gas- solid reactions such as oxidation, hydration, or carburization.
- INCORPORATED BY REFERENCE may adsorb onto surfaces first, then react and crystallize, or may form above the surface and deposit by solid-surface tension forces prior to reaction and crystallization.
- Post-CVD treatment e.g., annealing may be conducted to improve the quality of the film or film-tip/film-tool adhesion.
