CVD Coating Services — Industrial Solutions

A CVD coating is a protective surface layer created through chemical vapor deposition or related high-temperature diffusion processes. The coating forms a strong bond with the base metal, often creating an intermetallic compound or hardened surface. In industrial use, CVD-style diffusion coatings improve wear resistance, corrosion resistance, oxidation protection, and component life in demanding operating environments.

PVD coatings are typically deposited physically in a vacuum at lower temperatures, while CVD coatings rely on chemical reactions at elevated temperatures to create a bonded coating layer. PVD is often used for thin, precise decorative or wear coatings. CVD and diffusion coatings are commonly chosen when deeper metallurgical bonding, high-temperature stability, or severe corrosion and erosion protection are required.

Components exposed to heat, abrasion, erosion, oxidation, corrosion, or chemical attack are strong candidates. VaporKote supports heat exchanger tubing, fasteners, reactor screens, pump impellers, pump wear rings, sleeves, bushings, valve components, gears, shafts, and large machined parts. The goal is to protect surfaces that directly affect uptime, efficiency, sealing performance, and equipment replacement costs.

Aluminizing is generally used when high-temperature oxidation and corrosion resistance are the priority, such as heat exchanger tubing, fasteners, wire cloth, and reactor screens. Boronizing is selected for extreme wear, erosion, and abrasion resistance, especially on pump components and other surfaces exposed to friction or abrasive media. VaporKote reviews the application before recommending the best process.

Yes. VaporKote has state-of-the-art furnaces for aluminizing and boronizing large components, plus machining capabilities for parts up to 68 inches in diameter. This is valuable for industrial customers that need coating performance without compromising dimensional requirements, close tolerances, or the practical realities of maintaining large pumps, processing equipment, and specialty components.

VaporKote serves industrial customers in manufacturing, petrochemical refining, oil production, oil drilling, mining, aerospace, agriculture, pulp and paper, and heat exchanger manufacturing. These industries often operate equipment under heat, corrosive chemistry, abrasive media, or continuous-duty conditions. Protective diffusion coatings help extend component life and reduce maintenance-related production interruptions.

VaporKote adheres to ASTM, ASME, SAE, API, and other engineering codes and practices where applicable. The company also provides metallurgical analysis and certification of diffusion coatings. This technical approach helps customers make coating decisions based on material behavior, performance requirements, and critical-service expectations rather than generic surface treatment assumptions.

Start by sharing the component type, base material, operating temperature, process media, wear or corrosion issue, dimensional constraints, and any applicable engineering requirements. VaporKote can review the application and recommend an appropriate path, such as thermal diffusion coating, aluminizing, boronizing, nitriding, heat treatment, machining support, or a combined solution for improved reliability.
