HVAF PROJECTION

All types of process can use metal coatings, depending on what mechanical properties you want for your parts. However, HVAF projection allows the densest coatings on the market, exceeding conventional HVOF systems.

WIDE RANGE OF CARBIDE AND METAL COATINGS

These coatings are used to rebuild worn parts. It is also possible to rebuild a part using a metal coating, then apply a carbide finish.

METALLIZATION WITH METALLURGICAL LINKS

Through this process, we have the ability to create more flexible metallic coatings that can withstand wide temperature variations while maintaining excellent properties against corrosion and abrasion.

EGI HVAF Process Overview HVAF: High Velocity Air-Fuel Description HVAF or High Velocity Air-Fuel is a thermal spray process for deposition of coatings for protection of parts, vessels and structures against abrasion, erosion and corrosion. Common uses:

• abrasion protection • chemical resistance • erosion protection • corrosion protection • surface restoration • diameter build-up • spraying of internal diameters of pipes • thin layer surface alteration to prepare for other processes such as galvanization • surface preparation by cold or hot grit blasting • coating stripping by hot grit blasting

EGI HVAF PROCESS HVAF is a warm spray process that is cooler than HVOF. Our guns utilize axial powder injection into an air-fuel jet with a temperature of about 1800-1980°C. Therefore, the process is capable of effectively applying carbide-based materials, the HVAF process can also apply metals with almost zero oxidation. All common thermal spray powder materials may be applied with HVAF. Different coatings, Powders and Deposits: EGI HVAF can apply metal, carbide, and metal alloy powders of 5 to 53 micron range, with -30+10 µm cut being the most common. The deposit efficiency (D.E.) is 50-75% for carbide powders, and 60-85% for metal powders. Spray rates and specifications: HVAF process is capable of spray rates of up to 40 kg/h of carbides, and up to 33 kg/h of metal powders. Tungsten Carbide Application Tungsten carbide and Ceramics are the predominant material applied by HVAF for abrasion wear and Chemical resistances. With -30+10 µm powder cut, coating hardness of up to 65-90 RCW.


Wear and Chemical Resistance: Tungsten carbide and ceramics (86WC-10Co-4Cr) HVAF coatings demonstrated 90-185% higher wear resistance when compared to regular cold thermal sprays.

Bonding Strength HVAF coatings generally have very high bond strength. For HVAF-sprayed WC-based coatings, with or without grit blasting, the typical bond strength exceeds 12,000 PSI, which is the limit of regular glue adhesion bond strength testing equipment. EGI HVAF coating bond strength is not conventionally measurable due to preliminary glue failure in normal testing equipment. Alternative braze adhesion bond strength testing was developed, which determined the bond strength of HVAF-sprayed Inconel 918 to be 31,000 PSI (200Mpa).

Fatigue, Impact and Stress Resistance A notable characteristic of our HVAF coatings is the resistance to stress-induced delamination. Coatings are non-brittle and are capable of withstanding significant mechanical deformation, as high bond strength to substrate prevents peel off. In many cases thermal spray is applied manually, this technology does peal off as the coatings have not fused to the parts as done with our automated HVAF machinery. In testing


substrates with tungsten carbide coatings were bent at 90° over 0.5" diameter, yielding no coating delamination. In alternative tests, coated samples were stretched to failure. Impact Resistance

As with fatigue and stress testing, HVAF coatings exhibit very good impact resistance. In an impact test a 1 lb steel ball was dropped from a height of 5 feet. Typically HVOF and supersonic plasma can withstand 18-22 hits before failure, as shown in plasma WC/20Cr3C2/7Ni coating on the left. On the right is an HVAF with our coating sprayed with our spray gun withstood 100 hits and the test was stopped. Permeability The Tungsten carbide based and chrome carbide based HVAF coatings sprayed with HVAF system were determined to be impermeable in 15,000 PSI gas-permeability testing, as sprayed. Coating Thickness Carbide HVAF coatings can be routinely deposited to 1000 µm thickness, with up to 40-50 µm applied per pass. In testing up to 12,000 µm coatings were achieved with tungsten carbide. Metals can routinely be applied to 8000 µm thickness or more, with 100 µm applied per pass. The photograph below shows a 8mm thick tungsten carbide coating.


Resistance to High Contact Loads Our coatings sprayed with our spray system can withstand 3.5GPa contact pressure, which is 75% higher compared to what the other best coatings could provide in comparative testing.

Corrosion Resistance EGI HVAF coatings can be corrosion resistant "as sprayed" with no additional sealant application.


Coating Internally (I.D) Our HVAF spray guns can shoot as small as 55 mm can apply coatings to internal diameters of pipes and parts as narrow as 80 mm. With no inherent restriction on length, pipes as long as 80 ft and more can be internally coated.
