specialty coatings have applications
in aerospace, power generation, manufacturing, marine, mineral, mining, oil and gas and waste treatment industries. The coatings are low cost and can easily be sprayed
at room temperature on different materials, such as metals, ceramics, concrete, plastics, composites and fabrics.
AS&M's coatings have been developed for challenging applications of wear, fretting and erosion.
Erosion is a particularly challenging problem. It occurs in environments laden with dust or with windblown sand or with particulate laden fluids. The problem lies in dissipating the energy of the impinging particles. To avoid erosion, the energy of the impinging particles needs to be dissipated in an effective manner. Hard materials tend to be erosion resistant because of their high specific strength. But even hard materials are affected by impacting particles. Each time a particle strikes, some of the energy is dissipated by forming micro cracks in the hard material. Eventually the micro cracks link up and the surface of the hard material essentially shatters coming off in little chips. AS&M’s AeroKret coatings are made of a soft but resilient material. It avoids erosion by dissipating the energy of impacting particles as heat. Because of its design, it is highly resistant to erosion. It is also flexible and can be used to protect soft and flexible materials such as fabrics as well as solid objects. Even materials normally considered to be erosion resistant, such as concrete, glass, stainless steel and even tungsten carbide benefit from the protection afforded by AS&M’s coatings. The coatings are chemically inert in most environments and can be used at elevated temperatures of up to 400°F for extended time.
