Selective plating, with the SIFCO Process<sup>\u00ae<\/sup> creates a powerful atomic bond which is resistant to cyclical temperature fluctuations and sharp, direct impact. The durability of your surface coating is most important if that coating is subject to a corrosive environment. Assuming that base material is properly prepared, tests run in accordance with ASTM C633\u201113 on the SIFCO Process<sup>\u00ae<\/sup> show that two commonly used nickel deposits had a bond strength exceeding the strength of cement. Furthermore, selective plating provides a precise deposit thickness, while thermal sprayed parts require machining to the required dimension.<\/p>\n<p>If you are having problems with adhesion, determine if your application may be suitable for selective plating.
