At Longevity Coatings, we pride ourselves on our in-depth knowledge, our long experience and our innovative uses of new technology, all of which come together in meeting your particular coating challenge.

The Consultation

Longevity Coatings is dedicated to providing the highest quality service to our customers. The starting point for achieving that goal is an up-front consultation with one of our coatings professionals. Longevity engineering consultants will assess your needs and its unique challenges; we will then recommend  the material, the process and the process parameters that will get the job done efficiently and cost effectively.

The Processes

Drawing on our lengthy experience in the field, we have designed our own coatings application equipment. This innovative equipment incorporates advanced digital motion control technology with modern  thermal spray technologies to produce the most consistent coating in the industry today. We have brought mass production technology into a job shop environment and, as such, are able to spray a wide range of short or long run jobs.

Although computer-controlled processes are common in large manufacturing plants, it is rarely found at the job shop level; in effect, we have brought mass production technology into a job shop environment. We are able to spray a wide range of short run jobs. involving  inside diameters, outside diameters and complex shapes.

Our computer-programmed spray equipment allows us to apply coatings to carefully defined areas of the substrate.  we can precision spray inside diameters, outside diameters and complex shapes alike. When wear resistance is the chief objective, a thermal coating can be directed and applied only to those surfaces subject to wear. The cost of coating an entire component is thus eliminated.

We employ a variety of thermal spray coatings processes, including: HVOF (High Velocity  Oxygen Fuel); Plasma coatings (Non-transferred arc); Twin Arc and combustion flame spraying; and fused coatings.

The Coating Materials and exotic substrates

Not all coatings materials are created equally. Some of the earth's most exotic alloys-- for example, Tungsten, Molybdenum, Chrome Carbide, etc.- have unusual properties which must be taken into consideration. Most of these advanced coating materials are costly and difficult to handle; for this reason, not all coatings companies are willing or able to apply them.

Tungsten carbide is another example. Unformed tungsten carbide from two different suppliers may have the same composition, but may have different properties-- depending on the process used to produce the raw material. To ensure quality, uniformity and product consistency, we require suppliers of our ceramics and tungsten carbide raw materials to adhere strictly to our own specifications and to certify each shipment.

Not only do coatings materials have their own unique characteristics; the same is true for base materials (substrates), which accept coatings in different ways. Thermal expansion rates, metal corrosion issues, flash oxidation and many other pertinent concerns are carefully evaluated during the consultation process to avoid unwanted results

At Longevity Coatings, our state-of-the-art equipment and in-depth experience enable us to apply these top quality materials to your exotic components, allowing you to benefit from their unique properties.

 Spray dryer vessel that was ceramic coated to meet materials compatibility issue for manufacturer of nickel-cadmium batteries. Also coated for this project were related ancillary components, including valves, mixing machines, hoppers and mixing agitators. Because any contaminant—whether from the stainless steel interior of the vessel or from the ancillary components-- could adversely affect the performance of the batteries, all surfaces were coated with an aluminum-oxide (A_l2O₃) coating. The coating not only protected the battery components from contamination; it also added extreme wear-resistance to the processed parts
