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.
The final appearance of the chromate film depends on the base metal smoothness and the quality of the plated deposit. The duration of protection provided by zinc coatings is a function of: coating thickness, exposure conditions, post plating treatments, and chromate post sealers.rom this consideration alone, application of a chromate coating is advisable. Figure 1 In general, chromates are applied by immersing the zinc-plated parts in a solution containing dichromate, or chromic acid and an activator (usually, nitrate, sulfate, chloride, formate, or fluoride).
