We are unique in our ability to work with our customers and provide them with a custom engineered solution for their specific surface engineering requirements.
When a customer describes their components desired surface properties, We use our extensive materials engineering expertise to assure the optimum coating is designed to meet or exceed the components specific needs. After a coating solution is developed our production engineering expertise is used to produce the coating in typically medium and high volume - accomplished using our thorough understanding of thermal spray processes and the many methods to automate them.
Coating Design & Development
Our materials engineering team has over 60 years of thermal spray coating design and development experience. When a customer contacts our engineering staff with a potential coating application, We use our expertise to first understand the environment the coating will be used in, and then design the properties required to withstand the environment.
In order to achieve the optimum coating properties for each specific application, we collaborate with our customers during the coating development and testing phases. Our customers become educated about the coating materials that we recommend and how the component's design can be used to get the most out the coating properties. Combining a well engineered coating material and component design results in the component functioning in the optimum manner.
Development to Production Example
A food dispensing equipment manufacturer approached us about a rotating shaft in contact with a polymer seal designed to keep liquid from leaking out of a dispensing unit. The liquid contained a high sugar concentration, so if the device was not properly maintained, dried sugar would embed in the polymer seal and wear a groove in the shaft which led to leaking. The customer had tried many different ideas to solve this problem, including using expensive shaft materials so the shaft could be hardened by heat treating and employ hard chrome plating, but none prevented the the wear groove.
We engineered and tested a ceramic coating solution that was significantly harder than the sugar, which eliminated development of the wear groove. In addition, we collaborated with the manufacturer to redesign the shaft, since the coating now provided the required wear resistance, the shaft no longer need to be made from an expensive heat treated alloy. A softer, easier to machine alloy was selected and combined with the newly developed coating.
The final component design and coating not only eliminated the source of the leak, but resulted in a less expensive part with enhanced performance. This updated component has now been in production for many years with no reported problems.
