Boronizing (Boriding)
Ultra-hard boron diffusion coatings achieving RC75+ surface hardness—harder than tungsten carbide—to dramatically extend the life of components exposed to severe erosion, abrasion, and friction.
VaporKote has been engineering precision industrial coatings since 1987, delivering wear resistance, corrosion protection, and extended component life for industries from petrochemical refining to aerospace. Serving manufacturers, oil producers, and mining operations, our diffusion coating technologies—including boronizing, aluminizing, PVD, and thermal diffusion—help you slash maintenance costs and prevent costly downtime. Discover what 37+ years of coating expertise can do for your equipment.
Comprehensive coating solutions engineered to extend component life, reduce wear, and protect against corrosion across demanding industrial applications.
Ultra-hard boron diffusion coatings achieving RC75+ surface hardness—harder than tungsten carbide—to dramatically extend the life of components exposed to severe erosion, abrasion, and friction.
High-temperature aluminum diffusion coatings that deliver superior protection against oxidation and corrosion for heat exchangers, fasteners, wire cloth, and other critical components in thermal processing environments.
Versatile Physical Vapor Deposition coatings—CRN, TIN, AL-N, and ZRN—customized to each application's demands for wear resistance, corrosion protection, and thermal conductivity.
High-temperature metal powder processes that form metallurgical alloy coatings penetrating beyond the surface, offering outstanding wear and corrosion resistance in the harshest operating conditions.
Cutting-edge plasma nitriding technology that introduces nitrogen into metal surfaces to create a hardened layer, significantly improving wear resistance for gears, shafts, and precision industrial components.
Tailored thermal processing—including annealing, tempering, quenching, and case hardening—to optimize mechanical properties, relieve stress, and enhance the durability of metal components.
At VaporKote, every coating is engineered with one goal: maximizing the operational life of your most critical components. Our diffusion coating technologies—boronizing, aluminizing, PVD, and thermal diffusion—penetrate the base metal to form a true metallurgical bond, not merely a surface layer. Industries including petrochemical refining, oil production, mining, and aerospace rely on us because VaporKoted parts consistently outperform untreated materials and competing surface treatments, saving clients hundreds of thousands of dollars annually in maintenance and replacement costs. With state-of-the-art furnaces capable of processing components up to 68 inches in diameter and strict adherence to ASTM, ASME, SAE, and API standards, we deliver measurable, lasting results.

A dedicated team of coating specialists and engineers committed to industrial excellence.
Founded in Anaheim, California in 1987, VaporKote has spent over three decades earning its reputation as a transformative force in industrial protection. What began as a vision to redefine wear and corrosion resistance has grown into a comprehensive coating operation serving industries across petrochemical refining, oil production, aerospace, mining, and pulp and paper. Headquartered at 1270 N Grove St, Anaheim, CA, our Southern California facility houses state-of-the-art furnaces and advanced machining capabilities, enabling us to coat and manufacture large components entirely in-house. Our team of seasoned engineers and coating specialists formulate custom solutions—rooted in metallurgical science and strict adherence to ASTM, ASME, SAE, and API standards—ensuring every component we touch delivers measurable performance gains. At VaporKote, our mission is your longevity.
The most widely used industrial coatings include boronizing (boriding), aluminizing, PVD coatings (such as TiN, CrN, AlN, and ZrN), thermal diffusion (TD) coatings, and IonPlasma nitriding. Each serves distinct purposes: boronizing delivers extreme hardness for erosion resistance, aluminizing protects against high-temperature oxidation, and PVD coatings offer versatile tribological and corrosion-resistant properties for precision components.
