In contrast, the normal nickel-plating coating containing no microcapsules tended to lose weight during the experiment, and weight loss increased with time. This indicated that the release of microcapsules plays a substantial role in self-repair in the case of composite coatings that improve wear resistance. [Pg.327]

Figure 9.25(b) illustrates the polarized curve of the composite nickel-plating coating with or without abrasion (type 600 abrasive paper, 3600 movements). The results obtained revealed that the corrosion current on the surface of the composite coating containing antirust oil-encapsulated microcapsules was smaller after abrasion under the same anodic polarization potential. Abrasion of the composite coating surface ruptured the microcapsules such that the encapsulated oil was released and spread onto the surface. The polarization current was reduced that is, better wear and corrosion resistance was achieved if the microcapsules were... [Pg.331]

A principal commercial appHcation of the hypophosphites is ia the electroless plating (qv) process. Nickel salts are chemically reduced by hypophosphites to form a smooth adherent nickel plating to protect the iateriors of large vessels and tank cars. The coating, which can be hardened by heat treatment, usually contains 8—10 wt % phosphoms and is highly impervious. [Pg.375]
