VaporKote Boronizing (Boriding) Treatment Services

Energy, Aerospace, and other industrial companies understand the value of high performing parts that minimize maintenance and downtime. As one of the first providers of the Boronizing (Boriding) process, VaporKote has significantly decreased wear, erosion, and abrasion problems on numerous critical parts and equipment. Boronizing increases component wear life up to several times. Ensuring a very hard, wear-resistant surface, our erosion protection system uses a boron gas diffusion coating or "Boronized" process.

Boronizing (Boriding) is a chemical vapor deposition (CVD) pack cementation process whereby  boron atoms are diffused into steel and other substrates of iron, nickel and cobalt base alloys, forming an intermetallic compound at the surface base metal. Uniform diffusion case depths are controlled by the thermo chemical reactions. This boronizing treatment provides maximum resistance to abrasion, erosion, and wear – with negligible growth to the original part. 

Parts are metallurgically treated with our proprietary boron formulas, creating a new, very hard Boronized metal surface.VaporKote wear-resistant boron hardened components can be held to close tolerances and, if needed, secondary machining can be done at coated surfaces. Masking is done for areas not requiring a hard surface thus enabling the surface to be easily machined after boronizing. 

Pumps, valves, pipe spools, elbows, and other pipe components are routinely fabricated, welded, and boron-hardened for wear and erosion protection. Boronized parts are approved for critical aerospace components.  VaporKote also specializes in manufacturing “Boron hardened pump wear rings”–harder and more durable than heat treated, plasma sprayed, or stellite overlaid rings.

 Boronizing Metal Erosion Protection System Advantages         
● It is a powder borne process– not line of sight–so all areas are accessible.        
● There is no a void at the diffusion zone–it is 100% dense.     
● Boron diffusion forms strong metallurgical bonded surface alloys vs. weaker mechanical bonds with other systems.  
● Boronized coatings are harder than tungsten carbide.
● Boronized surfaces have a lower coefficient of friction vs. the base metal.  
● Less costly base metals can be boronized and will outperform more expensive untreated material.
● It is a high volume economical furnace batch process, thus cost savings.
● Previously boronized parts can be repaired and recoated.
