Advanced HVOF Alternatives

Benefits to HVOF Alternative Coatings

NLOS Advantage

Unlike the NLOS issues associated with HVOF, TriCom can be applied in small inside diameter bores. Once applied, it can be honed or ground to the final dimensions and surface finish.

Near Net Shape

Our processes do not distort thin metal components during electrodeposition and can be applied to near net shapes.

Aerospace Qualified

From the start, we understood how significant our coatings would be to the aerospace industry. We've gone through the long and rigorous testing processes to become aerospace qualified.

Superior Ductility

TriCom will bend and deflect with the part, therefore reducing the chance of delamination. Perfect for coverage on seals.

TriCom vs HVOF coating

Different TriCom HVOF coatings have been developed or modified for unique customer application needs in various markets, such as aerospace, power generation, gas turbines, oil & gas exploration tools, agriculture, and mining equipment. These efforts resulted in innovative coatings that provide the extraordinary advantages detailed below.

A Replacement For Thermal Spray Coatings

High velocity oxy-fuel spraying, often referred to as HVOF spraying or thermal spraying, is a coating method that spreads melted (or heated) particles onto a surface. This process results in a wear, corrosion, and thermal resistant barrier on the outer diameter (OD) of a structure. HVOF is readily used in several industries today including aerospace, automotive, oil & gas, and textile. However, the several limitations of thermal spray coatings spurred our research and development scientists to discover a breakthrough technology that is able to surpass HVOF standards without any of its disadvantages.

One of the many advantages that TriCom provides is the ability to coat non-line-of-sight (NLOS) areas like the inner diameter (ID) of a structure. Unlike HVOF, and other thermal spray technologies, TriCom will result in a better adhesion to the bonding area when coating the ID. After parts have been processed with HVOF, grinding or polishing is required to achieve the final dimensions. TriCom can be coated to near net shape with no distortion of the component during the coating process. Rarely is there a need for secondary operations that only increase time and cost. In addition, HVOF is a very costly process. TriCom customers have seen an overall cost reduction on their operations, not only due to the lower initial investment, but as a result of a longer lifespan from products in the field.
