BACKGROUND: A review of the literature showed that the core competencies needed by newly graduated Chinese nurses were not as of yet undocumented. OBJECTIVE: To develop a psychometrically sound instrument for identifying and measuring the core competencies needed by Chinese nursing baccalaureate graduates.
A&P here. Zinc chromate is used as a primer on aluminum surfaces as a conversion process to inhibit corrosion. Since nearly all modern aircraft skins and structures are made from aluminum, this compound and its derivatives are the most common primers seen in aircraft manufacturing.
Essentially, you can think of plating as a double protection system from corrosion for steel parts. Continuing research has developed a wide range of options regarding this protective coating. In many industries, zinc plating is standard on all parts. coating is added that with the zinc has a profound effect on the corrosion properties, significantly increasing the time to white rust.Colored chromates are some of the most effective corrosion protection that one can buy. Chromate colors in order of increasing corrosion resistance: White-Blue-Yellow-Black-Olive Drab.
