Cheaper brass coatings for aircraft parts and pipelines move closer to real-world field repairs

Researchers from Skoltech—a VEB.RF group institution—have, for the first time, deposited a brass-based composite coating with reinforcing particles on a stainless steel part using low-pressure cold spraying. The technique is cheaper than currently used alternatives, less harmful to the environment, and uniquely adaptable for repair work at infrastructure facilities in the field by mobile maintenance teams. Brass coatings are used to extend the service life of bearings and other metal parts subjected to friction in manufacturing, aviation, marine and railroad engineering applications, and on drilling rigs and pipelines.
