PROCEDIMENTO PER LA PREPARAZIONE DI COMPONENTI A BASSA DENSITA', CON SUBSTRATO EVENTUALMENTE COMPOSITO A MATRICE METALLICA O POLIMERICA, RIV |
摘要 |
<p>Process for the manufacture of 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 the following steps: optionally, matching the surface in order to generate residual compressive stress in the outer layers; optionally, thermal stabilizing at a temperature lower than 350° C.; depositing onto the outer surface, with hot spraying techniques at a temperature ranging from 70 to 350° 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 invention also relates to the low density components of high surface strength thus obtained. The FIGURE is a perspective view of a recirculating ball unit with the raceway P coated in conformity with an embodiment according to the invention.</p> |
