Abstract
Manufacturing low density components of high surface strength having a polymer or metal matrix substrate and ceramics and/or metal-ceramics coating, wherein the low density substrate to be coated is subjected to: optionally, machining the surface in order to generate residual compressive stress in the outer layers; optionally, thermal stabilizing at a temperature lower than 350.degree. C.; depositing onto the outer surface, with hot spraying techniques at a temperature ranging from 70 to 350.degree. C., of a coating layer in ceramics and/or metal-ceramics material of a surface strength higher than that of the component to be coated, the surface of the coating layer being optionally subjected to a finishing treatment. The disclosure also relates to the product thus obtained.
