Precision Thermal Processing — Industrial Heat Treating Services by VaporKote

VaporKote's thermal processing services are compatible with a wide range of ferrous and non-ferrous metals, including carbon steels, alloy steels, stainless steels, cobalt-based alloys, and nickel-based superalloys. The specific treatment recommended—boronizing, aluminizing, ion plasma nitriding, or thermal diffusion coatings—depends on the base material composition, the component's operating environment, and the desired performance outcome.

Boronizing achieves significantly higher surface hardness than carburizing or gas nitriding, reaching RC75+ equivalency (1500 Knoop hardness)—harder than tungsten carbide. This makes it uniquely suited for high-erosion and high-abrasion environments. Carburizing and nitriding produce softer case hardness layers (typically RC55-65) and are better suited for impact-resistant applications, while boronizing excels where abrasive wear is the primary failure mode.

VaporKote serves a broad range of heavy industries including oil production, petrochemical refining, aerospace, mining, agriculture, pulp & paper, and heat exchanger manufacturing. Any industry relying on metal components exposed to elevated temperatures, corrosive media, abrasive fluids, or high-friction environments can benefit from VaporKote's precision thermal processing and diffusion coating solutions.

Processing timelines vary based on the treatment type, component size, and batch volume. Standard thermal processing cycles typically range from 24 to 72 hours of active treatment time, with additional time for metallurgical analysis, quality verification, and documentation. VaporKote prioritizes rapid turnaround to minimize customer downtime, and specific lead times can be confirmed during the initial consultation.

VaporKote adheres to ASTM, ASME, SAE, API, and other recognized engineering codes and practices across all thermal processing operations. Each treatment cycle includes metallurgical analysis and certification of diffusion coatings, verifying surface hardness, coating thickness, and diffusion depth. Full documentation is provided with every processed component to support your quality management and regulatory compliance requirements.

VaporKote's state-of-the-art furnaces are capable of processing components up to 68 inches in diameter, making it one of the more capable facilities for large industrial parts. This includes large pump impellers, heat exchanger tubing bundles, reactor screens, and other oversized components that exceed the capacity of most standard heat treating facilities. Contact us to confirm suitability for your specific component geometry.

Results vary by application, but VaporKote's boronized and aluminized components consistently outperform untreated parts and other surface treatments. Customers report dramatic reductions in replacement frequency and maintenance costs—in some cases saving hundreds of thousands of dollars annually. The ultra-hard boronized surface resists erosion and abrasion far longer than conventional coatings, making the investment in thermal processing highly cost-effective over time.

Yes. VaporKote processes both new components prior to initial service deployment and existing components being reconditioned after wear. The company also manufactures precision-machined parts in-house—including pump wear rings, sleeves, and bushings—and applies boronizing or aluminizing treatments during the manufacturing process, offering a fully integrated solution from raw component to coated, ready-to-install parts.
