Component Enhancement

Many components are enhanced with flame spray coatings for hard surfacing, heat resisting, and close tolerance control. Other applications would include particle retention, EFI shielding, and grip advancement. Many industries can correct dysfunction through surface engineering technology or increase limits of operation in production and technical arenas. With hundreds of coating materials we offer component enhancement possibilities for any industry. Let us assist you to un-tap the unique needs your industry is reaching for.

Aluminizing

Aluminizing is a form of corrosion control for outdoor and salt air protection. We aluminize specialty construction and building works to provide longevity and corrosion armor. One application is the first responders key box for commercial buildings. We aluminize the components prior to paint to add outdoor fortification from the elements. Other applications include rod iron pool and garden fences and gates. Aluminizing is also used for iron bridge and girder construction for its protective shield.

Diameter Restoration

As components become worn or corroded, the cost of replacement can often be avoided by coating and machining the part so it can be returned to service.

Whenever we perform any type of dimensional restoration at Accuwright, we select coatings that most closely resemble the material from which the part is constructed, ensuring optimum compatibility and performance. Of course, we factor in color and aesthetics when needed, but more importantly, we take great care to select coatings that can improve the part or area of service.

Dielectric Coating

Various industries, electronics included, appreciate the value of dielectric coatings. Our plasma spray application has the capacity to spray at elevated temperatures required by ceramic materials. Although the process temperatures are high enough to melt the ceramics, the part substrate temperature is kept within safe working zones. Alumina coatings provide high dielectric strengths, which make them particularly suitable in the Electronics industry. Plasma sprayed coatings typically produce 450 to 500 volts per mil.

Hard Surfacing

Hard surfacing is provided by several of our spray processes. Some materials contain a material matrix of chrome or tungsten carbides that offer unmatched wear resistance. These coatings provide a surface treatment in many cases that can only be applied by the thermal spray applications. Industry standards have shown the HVOF application to exceed the wear capacity of chrome plating. Some industrial companies are replacing the old chrome plate process with the advantages of these thermal spray High Velocity Oxygen Fuel practices. Dense coatings such as these provide surface engineering solutions to many machine tool applications.

Abrasive Wear

When particles move across a surface, abrasive wear occurs. Damaging particles can be loose or attached to another part. This type of wear occurs in multiple industries ranging from automotive to aerospace, where it is common for pistons, hydraulic rods, gears and other apparatus to experience wear from changes in temperature, load, lubrication, etc. Flame spray processes such as High Velocity Oxygen Fuel Spray create an excellent alternative to component replacement because of the broad selection of available materials, quick turnaround and low cost.

Repair Coatings

At Accuwright Industries, we provide repair coatings for many gas turbine engine repairs. Most repairs are previously developed by engine manufacturers, however, we can offer recommendations based on our experiences for many components that do not have developed procedures. Other industries find benefit to refurbishing machine parts with the flame spray processes as well. We are able to bring years of aerospace practice to introduce coatings for repair of common machine tools and components.

Flame Spray

Flame spray is a term used in the coating industry to describe many of the Thermal Spray Processes. Because of its connotation, it is often used loosely as a general synonym for all of the metal spray processes. These include, but are not limited to the following: Read more...

Plasma Spray

Our Plasma Spray processes achieve high temperatures to melt and spray exotic metal and ceramic materials. Coupled with accelerated velocities, plasma sprayed coatings are dense with low oxide levels. Bond strengths are superb and coatings are reliable and consistent. Many of our industries served require the elevated quality Plasma Spray coatings can provide. When we use robotic spray capabilities with the Plasma Spray process, our coating integrity is impeccable.

Thermal Spray

Our Thermal Spray processes mostly include the Oxygen Fuel applications applied with wire or powder. Although many coatings are now replaced with greater energy and velocity processes such as Plasma Spray, there are still materials that are best applied with this lesser process. Some coating types, like the Nickel Graphite abradables, can only be applied with Thermal Spray Oxygen Fuel systems to achieve the correct hardness required. We are still expert at these processes because sometimes it is the only way to make those coatings correct.

Abradable Coatings

When a rotating part rubs against its shroud, inefficient and dangerous conditions can result, including changes in temperature, grooving and rupture; however, thermal spray processes can be used to appy abradable coatings, making this interaction not only tolerable, but safer and more efficient.

Metallizing

Metallizing is an old process word with today process meaning. Characterized mostly by the Twin Wire Arc Spray processes, it implies a metal coating. At Accuwright, we metallize a variety of components from Automobile parts to "high tech" sputter machine tooling. We can virtually metallize any substrate. Just remember, our metallizing processes are generally rough in the 'as sprayed' condition. You won't find value in trying to bronze baby shoes this way.
