The Ionbond™ CVD coating process, developed in the early 1970s, utilizes metal halides as coating precursors, including titanium tetrachloride (TiCl4) or aluminum trichloride (AlCl3). Over time, the technology has seen continuous improvements to meet the growing demand for high-quality, reliable coatings and enhanced productivity of both the process and equipment. The CVD coating process deposits coatings between 5 and 12 µm thick, and in special cases, up to 20 µm. Coating materials such as titanium carbide (TiC), titanium carbonitride (TiCN), titanium nitride (TiN), and aluminum oxide (Al₂O₃) are applied as single or multi-layers on inserts for cutting applications, forming and molding tools like punches, extrusion and trimming dies, and various mechanical components exposed to abrasive or corrosive environments.

For those comparing PVD and CVD options, Ionbond offers both PVD CVD coating services, allowing clients to choose the best fit for their needs. Whether you are interested in PVD, CVD, or a specialized PVD CVD coating, Ionbond can tailor the process to your product's unique requirements. Contact us to explore our Chemical Vapor Deposition services.

Typical lead times for both PVD and CVD coating services are usually 3 to 5 days. Test parts and sampling may take additional time for fixturing and process design.

Prior to coating, substrates (tools and components) must be free of foreign substances, oils, or grease on all surfaces, not only those to be coated. Proper cleaning is critical for optimal adhesion and maximum CVD coating performance. Ionbond’s process includes a thorough cleaning phase, and we encourage clients to discuss the ideal preparation for their specific substrates.

Headquartered in Bethesda, Maryland, Lockheed Martin Corporation is a global security and aerospace company that employs approximately 116,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products, and services.

The typical process temperature for Ionbond™ CVD coatings ranges from 900 to 1050 °C for HT CVD and 720 to 900 °C for MT CVD. Suitable substrate materials include tungsten carbides, tool steels, high-temperature nickel alloys, ceramics, and graphite. Tempered steel tools and components may need heat treatment post-coating to restore hardness.

Masking is generally easy with PVD, a line-of-sight process, while masking for PACVD is more challenging, and for CVD it is quite difficult. Contact us to discuss masking options for PVD and CVD coatings.

The Kennametal HARVI solid carbide end mill portfolio is an industry staple because of its ability to outperform other end mill tools when working on hard-to-machine aerospace materials like titanium and Inconel.

Kennametal Inc. announced today that its HARVI™ solid carbide end mills will be included as a preferred product in Lockheed Martin’s internal machining guide. The resource, produced by Lockheed Martin Aeronautics’ Operations Technology group for internal operations and engineering, as well as global supply-chain partners, identifies the most effective parameters and processes for machining material-specific aerospace components.

Chemical Vapor Deposition (CVD) is a coating method that creates low-stress coatings through thermally-induced chemical reactions. The coating material is supplied to the coating zone as vapor from the respective precursor, which then decomposes or reacts with additional precursors to form a thin film on the substrate. This CVD coating process can be done under vacuum or at atmospheric pressure, ensuring exceptional adhesion and uniformity. Ionbond also offers HFCVD diamond coating, a type of CVD diamond coating achieved by using a heated filament or wire to decompose hydrocarbon gases, providing additional options for clients requiring high-performance coatings.

“We’re honored to be a longtime supplier to Lockheed Martin and to have our HARVI III metal cutting end milling portfolio featured in one of its most invaluable machining guides,” said Keith Mudge, Kennametal Vice President Metal Cutting Sales, Americas. “We work closely with customers like Lockheed Martin to problem solve and deliver the utmost accuracy in machining. Inclusion of HARVI end mills in this internal resource is a testament to our commitment in the industry and our high standard of excellence.”

The CVD coating processes produce uniform and homogeneous coatings on the outside and the inside of the part or tool, which rests static in the chamber.

CVD coatings reduce long term costs and increase efficiency. Costs are reduced due to longer-lasting tools and increased cutting speeds and feeds, which results in higher productivity. CVD coated tools can be run with dry or with minimum lubrication (or release agents in the case of forming tools) saving both operating and recycling costs. CVD coatings on mechanicals reduce friction and wear and improve performance and reliability.
