Understanding HFCVD Diamond Deposition
The Hot Filament Chemical Vapor Deposition (HFCVD) process for creating diamond films is based on the following working principle: a carbon-containing atmosphere is mixed with supersaturated hydrogen, activated (typically by hot filaments), and then passed over a substrate. Under precisely controlled conditions—including atmosphere composition, activation energy, substrate temperature, and the distance between the substrate and the activation source—a diamond film is deposited. The nucleation and growth of diamond films are generally understood to occur in three stages:
- Activation and Transition Layer Formation: Carbon-containing gas and hydrogen gas decompose at a certain temperature into carbon, hydrogen atoms, and other active free radicals. These combine with the substrate to first form a very thin carbide transition layer.
- Diamond Nucleation: Carbon atoms deposit diamond nuclei on the transition layer formed on the substrate.
- Film Growth: The formed diamond crystal nuclei grow into diamond micro-grains under a suitable environment, and then continue to grow into a cohesive diamond film.
Key Advantages of Our HFCVD System & Nano-Diamond Coatings
The nano-diamond composite coating drawing die, utilizing cemented carbide (WC-Co) as the substrate, employs the chemical vapor phase method (CVD) to deposit a conventional diamond and nano-diamond composite coating on the inner hole surface of the mold. This results in a brand new product after grinding and polishing the coating. The nano-diamond composite coating not only exhibits the strong adhesion and wear resistance characteristic of conventional diamond coatings but also offers the advantages of a flat, smooth surface, a small friction coefficient, and ease of grinding and polishing inherent to nano-diamond coatings. This technology resolves technical challenges related to coating adhesion and overcomes the bottleneck of difficult-to-polish diamond coating surfaces, removing obstacles to the industrialization of CVD diamond films.

Specific Design Advantages of KINTEK's HFCVD System:
- Precision Mold Lifting Platform: For the parallelism and straightness of the mold lifting platform, our company has specially produced tooling. The biaxial lifting method allows the two ends to be raised and lowered by approximately ±0.02mm (2 wires), enabling the creation of smaller, high-precision molds.
- Optimized Tooling Integration: Our company integrates the location of each component on the tooling, focusing on the mold's tooling and process. This ensures good tooling and clamping, stable and reliable operation, high precision, and ease of use.
- Advanced Pressure Control: While other manufacturers may use baffle valves that cannot be adjusted linearly (gap increases quickly upon opening), our company designs the system with a shut-off valve based on principles of stable pressure control. This allows the shut-off gap to be linearly adjusted, achieving stable pressure control.
- Fully Automatic Control System: The system automatically controls pressure according to computer algorithms, reducing operator randomness and enhancing process confidentiality. This saves labor and ensures more ideal consistency in mold quality for the same specifications.
- Stable Bell Jar Operation: For the stability of the lifting bell jar, our company uses self-lubricating bearings, which make the rotation more flexible and free of jamming. The system is designed to accommodate each customer's specific diamond coating process requirements.
